I agree - it's far from satisfactory. If we were merely discussing bundled software then I could see that MS might not bust a gut to resolve the problem. But one of the failure points is with paid for Microsoft 365 Home (or whatever it's called now). The
Outlook application doesn't display the family (and probably any other) group. We may not be paying full O365 $ for it but it's still part of the subscription and it should work.
If MS didn't have a solution to the problem, then they shouldn't have broken the functionality that previously worked perfectly adequately.
