Not able to share health data
So me and my girlfriend both have iPhone 11s with iOS 15 (the latest version available) but we can share our heath data, when I try and add her, it’s says unable coz she doesn’t have a device to view it on, but she has an iPhone 11 with iOS 15….. when I try and add myself from her phone she can send and Invitation but I never receive it, I can send an invite to my mom(not that she’s accepted it yet) but I can’t send one to my dad who also says that he doesn’t have a device I can view it on? Can someone tell me what’s going on?
iPhone 11, iOS 15
