1.) There is a poor user interface at https://developer.apple.com/account/ because after purchasing there is always red alert "Your Developer Program Membership expires in X days. Renew your membership to keep your access to Apple Developer Program benefits and services.". After purchasing it should be hidden or changed to something "Your order is being processed" and hide button "Renew Memership" and do not allow to view order form again to avoid duplicate orders/payments. Red alert "Renew your membership" is there still after I have received email "Your order is being processed. Thank you for your order.". It is misleading.
2.) Why order process takes too long (several days)? Normally when order another stuff using card it is instant or takes only several seconds/minutes.
