I retried all your suggestions, made double sure that all local files on the tablet were deleted (I could only access my account via cloud), deleted my local files on my PC, reloaded the cloud ones and made sure Goat Person DLC was still there, then logged into cloud on the tablet and it still didn't work.

Do you think it has something to do with the fact that I bought the game and DLC from Gog.com?
I will be really sad if I can't access the Goatperson on the tablet.
