FYI folks, the new Self Service seems to have impacted the "Register with Microsoft" process. When performing the registration process the prompts to "open authenticator", "open self service", and "you are now registered with microsoft" are no longer displayed. The registration is successful, but since the "you are now registered" is no longer displayed, your users may be confused and try to redo the registration process. I created a case for this just now.
Thanks to everyone for posting the fix for the other issue (MANAGEMENT_ID) with 11.2 release of Self Service. That was super helpful in fixing our environment very quickly!
