This also happens on PC (Windows 7) and (Windows 10) - as well as Kindle and my phone app (Tracfone). I've noticed it for many months.
Reloading hasn't helped me - sometimes sneaking towards the photo from another direction works.
Or simply double clicking on the photo you want to access.
Hovering however - you almost always get the wrong member.
If I really want to look at the member profile I enter the member name in the search bar.
