Walkie talkie to invitations not working

I had the same problem and this fixed it. On the iPhone paired with the Apple Watch that is not working on Walkie Talkie, go to settings- FaceTime and switch FaceTime off. Wait a minute and switch it back on. When I did that, everything finally started working correctly. I rebooted the Apple Watch after doing that as well.

Hello dturner1112,

Thank you for posting in the Apple Support Communities. We understand that Walkie-Talkie invitations aren't being sent or received as expected, and reviewing the Apple Support article Use Walkie-Talkie on your Apple Watch was a great idea. We have a few more steps in mind that might help.

First, try restarting each iPhone and Apple Watch that's involved. This step sounds simple, but it can help reestablish the connection between the devices. Here's how to restart:

Restart your iPhone

Restart your Apple Watch

Next, try connecting the devices to another reliable network. This can help rule out a connectivity issue.

From there, we suggest making sure each iPhone and Apple Watch involved in using Walkie-Talkie is fully updated. If an update for the associated iPhone is available, we recommend making sure that an iPhone backup is made current via iCloud or a computer.
