We are looking to run a closed beta for our app - however what we are selling is premium video content, bought using an in-app currency.My question is, are we allowed to charge people outside of the app (e.g. through our website) to be part of the beta, whereby they get a testflight invitation and a certain amount of in-app currency. i.e. completely circumventing the app store at this stage. Down the line users will be able to purchase the in-app currency through the app or through our website.We're aware of guideline 3.1.1, "Apps may not include buttons, external links, or other calls to action that direct customers to purchasing mechanisms other than IAP." - which we are not in violation of by doing this.We more wondered if anyone had experience doing something similar and being explicitly forbidden to do so during beta since in-app purchase do not cost during beta, yet we are in a way, getting around this matter.Thanks
