Totally share and understand your frustration. It’s sounding like we all just need to go direct to Apple Support each time we experience a bug in the system. But also thank you for taking the initiative of troubleshooting this yourself and posting here so another user like me could know that my experience was not an isolated incident.
Depending on time and energy, it may be valuable for any of us who are tech savvy, and also have the motivation to post here, but also take the issue to the appropriate and direct online Support channels. And perhaps post the solution, or what was discovered back here on the boards to assist other users.
It would be nice if Apple could do this. But that may be too much to ask as they are probably short staffed like everyone else and also probably have too many layers of bureaucracy to implement our vision of the “ideal” any time soon.
Lastly I do agree with Eric that there are security issues at play when addressing things like this on a public forum. But definitely would have been nice if they led with that to direct us to the appropriate channel immediately instead of seemingly not even reading your question then supplying essentially irrelevant information within context of the original question.
