It looks like you're experiencing an issue where your custom form in Power Apps is not being reflected when you try to access it through SharePoint.
You can some of the following steps to troubleshoot and try to resolve this issue:
1. Clear Browser Cache:
- Sometimes, browser cache might prevent the updated form from loading. Clear your browser cache and cookies, then refresh the SharePoint site and try again.
2. Verify the Form Settings in SharePoint:
- Go to your SharePoint list.
- Click on "List settings".
- Under "General Settings", click on "Form settings".
- Ensure that "Use a custom form created in Power Apps" is selected. If it is already selected, you might try toggling it off and then back on to see if that forces the update.
3. Check Power Apps:
- Open Power Apps and go to the app you created.
- Ensure that all your changes are saved and published correctly. You can click on the “File” tab, then “Save” and “Publish” to make sure everything is updated and changes are being published.
- Go to "Settings" > "Support" > "Session details" and look for any errors that might indicate why the changes are not taking effect.
4. Permissions:
- Make sure you have the appropriate permissions to update and publish the form on the SharePoint site.
- Check if there are any permission issues on the SharePoint list or Power Apps that might be preventing the updates or changes from being applied.
5. Check for Multiple Forms:
- If there are multiple custom forms associated with the list, ensure that the correct or the main one is set as the default form.
6. Refresh Data Source:
- In Power Apps, go to "View" > "Data sources", and refresh the SharePoint list data source to ensure that the latest data is being used.
7. Browser Compatibility:
- Check if you are using a supported browser for SharePoint and Power Apps. Sometimes browser compatibility issues can cause an error.
8. Sync Issues:
- Sometimes, there might be a delay in synchronization between Power Apps and SharePoint. Wait for a few minutes and then try again. (This always gets me, sharing from experience)
9. Inspect Developer Console: (if you don't know how to access ask for help)
- Open the developer console (usually by pressing F12 in your browser) and look for any error messages that might indicate what is wrong when the form is being loaded.
10. Power Apps Environment:
- Check if you are working in the correct Power Apps environment. Changes made in one environment won't reflect in another.
If after trying these steps the issue still persists, you might need to:
Recreate the form from scratch to see if the issue is specific to the form you initially created.
