Can’t even use the Walkie Talkie

This is from the Apple support page. Fixed the issue for me:

If you're having issues with sending and receiving invitations

1. On your iPhone, open the Settings app, then tap FaceTime. Make sure that you're signed in with your Apple ID. Under You Can Be Reached By FaceTime At, make sure that your email address is selected.
2. Restart your Apple Watch.
3. Restart your iPhone.
4. Try to send the invitation again. On your Apple Watch, open the Walkie-Talkie app, swipe left on the contact, then tap . Tap , then choose the same contact.

iPhone x with Apple Watch 3 with cellular.Same problem. Rebooted my watch from out of the box. Removed FaceTime and reinstalled it. My contacts came up missing when I rebooted my watch3 I have my contacts back but I’m still unable to send out invites or received invites says that the person I’m inviting doesn’t have a Apple Watch (they do and it’s a series 3 as well) and when an invite is sent to me, I don’t receive it...

Have tried this resolution 20 times on both watches and no resolution. Signed out of Apple ID on both devices and no resolution. Have reset both watches and no resolution. I am at a loss.

Same issue here. I even unpaired my watch and then paired it again. Having a hard time finding a solution

Hi everyone,

I too was having this problem and was just able to fix it. I opened the apple watch app on my phone and went to the walkie talkie app within there. I deleted the contact I had sent a request to then re-sent a request (via the watch). He received the request right away and now it works.

I only had sent to 1 contact to test it out so not sure if you'll have to repeat this step for every new contact, but it worked for my initial walkie talkie contact. Hope this helps.

I am having the same issue on 2 gen 3 apple watches. one is mine and one belongs to my wife.

I was so excited about this so my husband and I can use it while we are at work. I have invited him and it says he doesn't have an Apple watch which he obviously does. He sent me an invite and I haven't received it. My watch is now showing Invited under his name and the same for me on his watch, but neither of us has actually gotten and invite to accept.

same problem. fixed it immediately with @ashcase method above.

Removed FaceTime from both phones. Power cycled all devices. Added FaceTime to both phones again and made sure to select add Apple ID to faceTime was checked and got notification and am able to use Walkie Talkie now.

my wife and i both have series 2 apple watches with no results on walkie-talkie invitations. also, i have a series 0 attached to my phone that yes, i know, watch OS5 isn't available for but i'm curious if this could be a culprit to our walkie-talkie continuous (inviting...) ?

Yes. A friend and I are both having the same problem.

Yep, exactly the same problem here. It says my contact was invited, but they've never received the invitation.

Same here. What good is a 6 months beta if one of the biggest new features has such a massive bug it makes it completely unusable?

Thank you, Ashcase. That worked for me.

This immediately solved my issue
