Describe the issue
While trying to lock in over the roon android and also Apple app, I am Everytime getting an 'invalid callback' message. Locking fails because the referral from your web based services to the respective app(s) fail. That's REALLY BORING!
Describe your network setup
My setup worked perfectly before!
Same region, same problem on all remote devices. Whenever I try to log into account.roon.app I get the “Invalidcallback” error.
