Hasn’t been working for me on any of the iOS 13 Betas.

I heard on a youtube video they disabled it due to a security issue, much like facetime a while back. However, that was the only place I heard about it, so I don't know if it's true or not.
 
It has been restored in the latest release version of iOS but apparently not yet in the beta of 13
 
Cant speak for the beta's but Apple's Supposed 12.4 fix for the exploit after disabling the feature didn't fix anything for myself and the one other person I used to use the feature with.

Picking the contact and sending invites from either party does nothing. No invite is sent or received from either end even though it shows the contacts walkie talkie card as greyed out with "Invitation Sent".

Tried resetting network settings, rebooting all devices several times, deleting the invitations and resending, changing the contacts phone number category from "mobile" to "iPhone" in the contacts app, logging out/in of FaceTime & iMessages, and even have completely reset and re-paired both Apple Watches. Nothing has worked.

Bummer we found it to be a pretty useful feature.

The other person isn’t on iOS 13 are they? It kills it. I went back to 12.4 on me and my Wife’s phone and made sure both are on the latest watch os (No beta) and they work like they should again.
 
Yeah, it must be an ios 13 thing, as I know a user on ios 12 that has no problems. I just downloaded beta 7 and still no luck.
