Expected behaviour

Establish the call

Actual behaviour

After opening Talk i see my last used chat. I click start call. The call rings, the other party answers, the calls drops and reconnects. Reconnection repeats, no call can be established.

CTRL Shift L didn't provide any logs. Shortcut seems to not function.

Only after a closing the app completely (clearing from ram) and opening it it would work as expected.
I think there might be a session issue after a longer break. If the app would simply force refresh if sessions timed out it might be solved. The server side works fine.

Start by reproducing the Windows 11 sequence: leave Talk minimized through standby for a day, then try to resume a call without fully closing the app. Trace the call and session handling after resume; done means the call establishes normally without restarting Talk, with useful diagnostics despite the reported shortcut problem.
