Description Of Issue
After updating to the last Roon version (core and remote) I cannot get into Roon.
It ask me to choose my Roon core and connect, then to login and then it tells me that I am already signed in but it won’t let me in.

Click “unauthorize” on that last screen. Sometimes there’s a sync problem.

Thanks! That solved it but now it is stuck in scanning.
On the same “838 Files Scanned” for the last 3 minutes or so.

Solved! Rebooting ROCK did the trick.
Scanning is done now.
