Started playing Pathfinder Adventures on iOS, done with the first 3 missions, but then I can't seem to be able to buy the rest of the game. On the world map, I click on the 'Burnt Offering" lock, which has a 'Store' button. But then clicking on that button has no effect, Is that expected? How would I get access to the DLC from iOS?

Be sure that you Are logged in game Center before playing in iOS system. The shopping should be possible after that. If it is not, then there is a clitch in there. But all in all the game Center account is the bonding key between you and the game account.

That was exactly my problem, Game Center was disabled in the iPhone settings! Now I have a big working "Store" button on the main screen. I guess you can consider the initial post a bug report, the "Store" button is not hidden everywhere when Game Center is disabled (on the map for example, and I think also on the character selection screen). When the button is hidden, having a notification somewhere that the Game Center must be enabled for DLC would probably be a useful hint Thanks for your help!
