I am new to all this but it seems GitHub has grey areas in the payment processing department i) I paid by card yet it asks for adding payment details - it should take payment details once and permeate through other areas of the application seeing we are talking about a single application ii) I have entered payment information but it seems to take a few hour before that effects as we are still blocked iii) what is the model here for payment I assume we pay subscription and have access for a period or however the application tallies usage but it seems to charge in addition to paying subscription
