As soon as i updated my mac mini to sequoia 15.6, the messages app has been super unreliable. sometimes conversations only show part of the thread, other times new texts won’t come in unless i open my iphone first. sending from the mac is hit or miss  some go through, some fail with the red exclamation point.

i tried signing out of messages, restarting, even re-enabling text message forwarding, but nothing seems to keep it fixed. it was working fine before the update so i’m guessing it’s tied to 15.6.
