We are struggling to launch an app that is specifically for Gynaecologists and Women's health practitioners. Part of the app is available to non members of our association, but there are specific parts of the app that require membership. Membership cannot be purchased via the app as there are some security checks that need to be done. Membership cannot be purchased with personal credit cards, and we do not "sell" the membership on the app. Users can apply for membership, and if they are part of this medical community (they have to supply their medical registration numbers and practice/hospital numbers, they can join. Only then will they be issued an invoice by the accounts department. Accounts are rarely paid for by individuals- they are usually paid by the practice to which the member belongs, or the hospital where they work. We have explained all of this but the reviewer does not seem to read the information
