I feel like I'm taking crazy pills because I can't seem to search for players by their username or view their profile so I can get their user ID to invite them as a friend. Plarium's page says, "You can also check the profile information of other players by tapping on their profile picture" but where can I do this? I'm playing on an iPhone https://9apps.ooo/  

Sometimes another player and I seem to team up well but in the Battle Log I can't click on anything to bring up their profile there (I don't think they're a bot because in Battle Log I also can't click on players that are in clans or on players I know exist IRL).

They don't always show up under Recommended and sometimes they aren't in a clan so I can't look them up in Clan List or Clan Power.

Thank you!
