Problem with Sharing in Fitness app

Hello, I use iPhone 14 Pro with iOS 17 Beta, my girlfriend use iPhone 13 with newest iOS 16. We used to use Fitness application to share our daily activity (steps, kcals etc.) Unfortunately last time our activity progress doesn't shows properly. In my phone I have 1000 steps for example, my gf see 0 steps. The same was at I was on iOS 16. Removing and invitating again doesn't help. What can we check?

Thanks in advance :)
