bobthealien replied to bobthealien's question in Pathfinder Adventures: Technical Support (Spoiler Warning!)That was absolutely the issue. I had Gamecenter disabled on my phone and it wasn't to get past that step. Turning on Gamecenter and then setting up my phone correctly allowed me to successfully join my iOS device to my Steam account copy.
I purchased The game and most of the expansions on Steam. Then I recently found out there is a mobile app for iOS. I looked at and followed the directions on https://forums.obsidian.net/topic/92893-how-to-merging-desktop-and-mobile-accounts/. After entering in the PFID and the Secret Key, the iOS app is locked on the screen saying Processing... definitely waited for 5+ minutes several times and I made sure to get a new Secret Key each time. My PFID is 419D4B760BF4248D
