This is Noris from Roon Lab Support here, I’d be happy to assist you here!
I want to start off by saying that what you are seeing with regard to the login behavior is abnormal, you should not have to re-login unless you have not verified your account for some weeks, so something else is going on here.
Can you please let me know the exact local time + date you see this re-login occur and also your setup details as per this thread?
