I’m so glad I found this thread! I’ve been having the same issue. I have successfully set them up on my iPad and my husband’s iPhone. The difference is that MY iPhone is using the iOS 26.1 Public Beta. My hunch is this is a bug between the Meta AI app and the iOS update. I’ve sent this back to Meta as well. Save your headache and pain until they fix this. I’ve spent HOURS pairing, unpairing, deleting, reinstalling, etc. it’s clearly an iOS 26.1 Public Beta issue for me. The only workaround would be resetting my entire phone and hoping I have a backup from before the latest iOS update. I think I’ll wait a bit before I go that route.
