Hi,
The issue of the coplilot app is not yet resolve as I confirmed today,
The copilot app when asked a question always return you need to login although you are already loggedin with microsoft account. This has been the issue many months ago though. I used to feedback to report the issue today.
The workaound is to use that browser, copilot.microsoft.com.
Where is the link to your FBH report?
I don't have any problem with the Copilot App, and I don't need any workaround. 🤷♂️
Try posting the question for your login problem directly to the Web Copilot and see what it comes up with. 😂😂😂
This app version 1.0.4.0 works fine for me.
