My Power App in SharePoint is not updating the UI

It sounds like you're experiencing a caching issue with your Power App on SharePoint. Here are a few steps you can try to resolve the issue:

1. Check for Updates: Ensure that you have published the latest version of your Power App after making changes to the UI. Sometimes, changes may not reflect until the app is republished.
2. Use a Different Browser: Try accessing the SharePoint page with a different browser or in incognito mode. This can help determine if the issue is related to browser caching.
3. Check Permissions: Ensure that you have the necessary permissions to view the updated app. Sometimes, permission issues can prevent the latest version from displaying correctly.
4. Validate SharePoint Site URL: If the SharePoint site URL has changed or been renamed, you may need to validate and fix the links associated with the Power App. This can be done in the SharePoint settings under Document Management.
5. Monitor Network Requests: Use the Power Apps Monitor tool to check if the app is making the correct requests to the server and receiving the expected responses. This can help identify if there's an issue with the app itself or the server.

If none of these steps resolve the issue, consider reaching out to the SharePoint Community or Microsoft support for further assistance.

Dear @Steven Suraine, 

Welcome to the Q&A Community.   

I understand how inconvenient it can be when your updated Power App UI doesn’t immediately appear in SharePoint.
