# Add-on loading Source: https://yamm.com/help/usage/troubleshooting/add-on-loading/ Fixes for YAMM loading problems — reinstall the add-on, recover when it freezes, fix a missing add-on menu, and what to do when only a Help button shows. ## Reinstall YAMM If YAMM doesn't work as expected and there's no specific solution, reinstall the add-on. Info: You can remove YAMM from the add-on store only if you installed it from the add-on store. If you installed YAMM from the marketplace, follow [Uninstall](https://yamm.com/help/usage/setup/uninstall/index.md). Open a new or existing Google Sheet. ![New Google Sheet open in the browser](https://yamm.com/help/images/docs/usage/troubleshooting/add-on-loading/how-to-reinstall-yet-another-mail-merge-1.png) Click **Add-ons** > **Manage add-ons**. ![Manage add-ons in the Add-ons menu](https://yamm.com/help/images/docs/usage/troubleshooting/add-on-loading/how-to-reinstall-yet-another-mail-merge-2.png) Click the three dots on the YAMM icon > **Uninstall**. ![Uninstall in the three-dots menu on the YAMM icon](https://yamm.com/help/images/docs/usage/troubleshooting/add-on-loading/how-to-reinstall-yet-another-mail-merge-3.png) Search for **Yet Another Mail Merge** and click **Install** to reinstall. ![Yet Another Mail Merge search result with the Install button](https://yamm.com/help/images/docs/usage/troubleshooting/add-on-loading/how-to-reinstall-yet-another-mail-merge-4.png) See [Install YAMM](https://yamm.com/help/usage/setup/install-yamm/index.md) for more. ## YAMM freezes or takes time to load If YAMM freezes, nothing appears in the pop-up, or no buttons respond, try these in order: ### 1. Try YAMM on another browser Browser updates can temporarily affect YAMM. Switch to another browser (e.g., Firefox or Safari if you're on Chrome). ### 2. Disable browser extensions Ad blockers and other extensions can block scripts. In Chrome: three-dots menu > **More Tools** > **Extensions**. ![Extensions page opened from More Tools in the Chrome menu](https://yamm.com/help/images/docs/usage/troubleshooting/add-on-loading/yamm-freezes-without-error-message-or-takes-time-to-load-1.png) Disable or remove the extension. ![Browser extension being disabled or removed](https://yamm.com/help/images/docs/usage/troubleshooting/add-on-loading/yamm-freezes-without-error-message-or-takes-time-to-load-2.png) ### 3. Sign out and log in with only one account Multiple Google accounts in the same browser cause conflicts. See [Log out from multiple accounts](https://yamm.com/help/usage/troubleshooting/quota-issues/index.md#log-out-from-multiple-accounts). ### 4. Try YAMM on another network Some corporate networks block YAMM. Try from home (no proxy). Workspace admins should whitelist `yet-another-mail-merge.com`, `googleapis.com`, `gstatic.com`, `cloudflare.com`, and `firebaseapp.com`. ### 5. Try YAMM in incognito Incognito mode bypasses cache, history, extensions, and ensures you're not signed in with multiple accounts. If YAMM works there, the issue is local — clean up cache and extensions. ### 6. Open your browser console and send us a screenshot In Chrome: menu > **More Tools** > **Developer Tools**. ![Developer Tools under More Tools in the Chrome menu](https://yamm.com/help/images/docs/usage/troubleshooting/add-on-loading/yamm-freezes-without-error-message-or-takes-time-to-load-4.png) In Firefox: menu > **Web Developer** > **Web Console**. ![Web Console under Web Developer in the Firefox menu](https://yamm.com/help/images/docs/usage/troubleshooting/add-on-loading/yamm-freezes-without-error-message-or-takes-time-to-load-6.png) In Safari: **Preferences** > **Advanced** > check **Show Develop menu in menu bar**, then **Develop** > **Show JavaScript Console**. ![Show Develop menu in menu bar option in the Safari Advanced preferences](https://yamm.com/help/images/docs/usage/troubleshooting/add-on-loading/yamm-freezes-without-error-message-or-takes-time-to-load-7.png) Click the **Console** tab. If there are JavaScript errors, they appear in red. ![Developer tools console javascript](https://yamm.com/help/images/docs/usage/troubleshooting/add-on-loading/yamm-freezes-without-error-message-or-takes-time-to-load-9.png) Send a screenshot via the [support form](https://support.yet-another-mail-merge.com/hc/en-us/requests/new). ## The YAMM add-on menu doesn't load properly A temporary issue, usually fixed within seconds. ### Only 'Help' is displayed in the add-on menu ![Only help menu](https://yamm.com/help/images/docs/usage/troubleshooting/add-on-loading/the-yamm-add-on-menu-doesn-t-load-properly-1.png) Refresh the spreadsheet and try again. ### The 'Open tracking report' button doesn't appear You see **Configure form submission notifications** instead, because YAMM isn't activated in that spreadsheet. ![Configure form submission notifications shown instead of Start Mail Merge](https://yamm.com/help/images/docs/usage/troubleshooting/add-on-loading/the-yamm-add-on-menu-doesn-t-load-properly-2.png) Click **Add-ons** > **Manage add-ons** > click **Manage** next to YAMM > **Use in this document**. ![Use in this document](https://yamm.com/help/images/docs/usage/troubleshooting/add-on-loading/the-yamm-add-on-menu-doesn-t-load-properly-3.png) Refresh the spreadsheet — **Open tracking report** appears. ![Open tracking report](https://yamm.com/help/images/docs/usage/troubleshooting/add-on-loading/the-yamm-add-on-menu-doesn-t-load-properly-4.png) ### The 'Add-ons' menu doesn't appear on my spreadsheet If the **Add-ons** menu is missing, you're probably looking at an Excel file (green `.XLSX` indicator at the top). ![Green XLSX indicator marking an Excel file rather than a Google Sheet](https://yamm.com/help/images/docs/usage/troubleshooting/add-on-loading/the-yamm-add-on-menu-doesn-t-load-properly-5.png) Open a new Google Spreadsheet (**File** > **New** > **Spreadsheet**), then **File** > **Import** the Excel data into the new spreadsheet. ![Import spreadsheet](https://yamm.com/help/images/docs/usage/troubleshooting/add-on-loading/the-yamm-add-on-menu-doesn-t-load-properly-7.png) ![Excel data imported into a new Google spreadsheet with File and Import](https://yamm.com/help/images/docs/usage/troubleshooting/add-on-loading/the-yamm-add-on-menu-doesn-t-load-properly-8.png) The **Add-ons** menu now appears. ![Add-ons menu visible](https://yamm.com/help/images/docs/usage/troubleshooting/add-on-loading/the-yamm-add-on-menu-doesn-t-load-properly-9.png) ## Only a Help button appears in the add-on menu When you open a spreadsheet, wait around 5 seconds for the document to fully load before using the add-on — otherwise you only see a **Help** button. Refresh the page a few times until the full menu appears.
