Activities Sharing not working

OMG what a nightmare. The activities app has to be the buggiest app ever. Either I can’t see a friends ring or they can’t see mine. Bloody nightmare. Even the text on the actual app on the iPhone is misaligned. It’s as if apple have asked some random company to design this app. It’s really poorly made. I’ve come from Fitbit and the challenges in that work flawlessly. You would think Apple would be the same. Does anyone know how I can make it work I just wanna share my rings with a friend and vice versa.
