Thanks to all for the input. It seems, the problem cannot be solved in a generic way. Except for apple would create an API function for it. The idea how we can solve: create 3 subscription types upgradable: IAProduct for 1 content -> align by internal token to align correctly e.g. $12,99 IAProduct for 2 contents -> align by internal token to align correctly to both contents, e.g. $24,99 IAProduct flat rate for all content -> no token necessary, e.g. $39,99 In that way, we can have as many community content as there is users can buy access to 1, 2 or 3andmore as upgrade function Disadvantage: All content must be aligned in an internal database that must be kept clear and errorfree. it seems to be necessary to show bought products in the account (new screen for payment transparency).
