"Hide Alerts" on iPhone does not hide group messages on the Apple Watch
I have seen this problem discussed various times going back to 2015, so I'm not terribly hopeful, but here goes.
I have an iPhone XS Max, Apple Watch 4 (no cellular). Both using latest OS. Selecting "hide alerts" for an iMessage thread works to silence the notifications for both the iPhone and the Watch when there is only one other person. But if there are multiple people in the thread, the alerts are coming through on the watch. Of course, these group threads are the ones that tend to be high volume, and so my watch goes crazy whenever one of these threads starts up.
My watch is currently set to "Mirror my iPhone" for alerts. Clearly this is not happening for group messages. I have seen the suggestion to unpair the watch or even wipe it and reinstall everything, and frankly that seems like swatting a fly with a sledgehammer. Anyone found a solution?
