As expected I had to re-login to Roon. Some remarks:
Re-login takes quite some time, about 40 to 60 seconds (estimate)
You need to re-login to Tidal too.
I had to reboot my Android phone (Galaxy A52s) before I was greeted with a login screen and able to re-login in Roon ARC. (shutting down Roon ARC didn’t help)
