you shouldn't have to wait if you paid. Unfortunately it is due to lag between the store payment and the store notifying me. Amazon sometimes takes 3 days to tell me it renewed the subscription for instance.
So, if you have an existing subscription, the trick is simple.
IMPORTANT: If you have an automatic subscription already, and this is IMPORTANT, it means you are not paying manually but that every month you get charged automatically, it can be solved easily.
The store will not charge you twice for an automatic subscription, it's impossible that you subscribe twice to the same product. So...
1) Try to automatically subscribe again.
2) The store will tell you that you are already subscribed and cancel the whole thing. You cannot subscribe twice.
3) The store will notify the game at that exact moment, no delays, of the error: he is a subscriber already.
Done, you can play regularly.
Again IMPORTANT this only works if you are on automatic subscription.
