Just wanted to check — was the issue with the “Built with Power Platform” not showing for shared users eventually resolved on your side after the propagation delay?
Also, did you need to make any additional changes (e.g., in Teams Admin Center or permissions) to fix it, or did it start working automatically after some time?
Appreciate your clarification!
The issue with User E failing to reinstall the Copilot Studio agent in Teams is caused by residual app metadata after using PowerShell to remove the app. To resolve:
Steps to fix:
%appdata%\Microsoft\Teams\Application Cache\Cache
Blob_storage
IndexedDB
Local Storage
tmp
"Your app package failed the validation"
The issue with User E not being able to reinstall the Copilot agent isn’t caused by browser cache or the web app. Since it only fails after the PowerShell uninstall, it’s likely due to stale app metadata on the Teams service.
To fix this:
Get-MgUserTeamworkInstalledApp
Remove-MgUserTeamworkInstalledApp
New-MgUserTeamworkInstalledApp -UserId <UserE-ID> -TeamsAppId <TeamsAppId>
