I have installed the updates on my iPhone SE and my Apple Watch. I have activated walkie-talkie on my watch. I’ve managed to add a few people. My wife, has the identical watch and phone. She has opened the walkie-talkie app on her Watch, but can’t get any further than the introduction that basically tells you what it does. It doesn’t present her with anywhere to add or a list of contacts. Has anyone else had this problem? Are we missing something?
