When you go to another person’s profile you can see their 3 equipped badges. There is also a “see all” button there, but if you tap it, it leads to your own badges, not to the badges of the person who’s profile you were viewing. This seems like a bug. I assume the button is not supposed to be there at all, but if it is, it should lead to that person’s badges.
Great catch, thanks for reporting this Miathan! I’ve passed it along to the team.
Cheers and happy battling,
