I registered and logged in at the registration screen after I updated to version 2.2. Everything was fine the first session. Then I closed it and opened it again, and then it was stuck on the registration screen forever (see screenshot). I cannot do anything besides closing the application. I created the support ticket STSP-3286, and the recommended me to downgrade back to 2.1. Now 2.2.2 is released, this problem is still not solved.
