Thanks for sharing the details, HannahKremsdorf-0379!
Sometimes the Phone Link account binding gets corrupted in Windows’ hidden Account Broker & Web Account Manager cache. When this happens, the UI behaves exactly as you described:
Continue button does nothing
Switch account flashes but doesn’t change
Reset/repair of the app does NOT fix it
You need to clear these Windows system-level identity caches, not just the app.
First, stop all Phone Link background services
Press Ctrl + Shift + Esc → open Task Manager
End these tasks if present:
- PhoneExperienceHost.exe
- Phone Link
- YourPhone.exe
- wsappx (if it’s running and heavy)
Next, delete the “IdentityCache” folder
Press Win + R, paste this:
%LOCALAPPDATA%\Microsoft\PhoneExperienceHost
Delete the folder IdentityCache (or everything inside that folder).
This removes the corrupted Microsoft account handshake data.
Next, clear Windows Web Account Manager tokens
Press Win + R, paste:
%LOCALAPPDATA%\Microsoft\TokenBroker
Delete EVERYTHING inside:
- Cache
- Identity
- TokenBroker subfolders
Don’t worry, these regenerate automatically.
Then restart Windows Account Sign-in Services
Press Win + R → type services.msc
Restart these services:
- Web Account Manager
- Microsoft Account Sign-in Assistant
- Credential Manager
Lastly, fully restart your PC and open Phone Link again.
Best regards,
Kimberly
