Messages app does not work after the Tahoe 26.3 update

The Messages app does not work after the Tahoe 26.3 update. Is anyone else having this problem?


When it starts, I am presented with a Sign into iMessage with your Apple Account dialog (which I have NEVER seen before). After signing in, Messages launches but quits with no warning or message and the Sign into iMessage with your Apple Account dialog appears again. And the cycle repeats...


Tahoe is a mess.

I did reinstall Tahoe and it did not help. After talking with a 3rd support person it turns out my Apple ID was flagged for spam so it was blocked from messages. They couldn't or wouldn't tell me when or why it was blocked and I had to submit a request to get it unblocked. I am still waiting for the results of that.


I asked how I was supposed to know my Apple ID was blocked and they did not have a good answer.

I was on a call with support and the recommendation is to reinstall Tahoe which I would rather not do. I see these messages in Console when signing in. Does anyone know what these mean? I replaced duplicate information with (same) to keep this under the 5K character limit
