According to the billing subscriptions documentation, there is a possibility of triggering a manual renewal before the current subscriptions has expired.
For eg. If I invoke the same purchase flow on a particular monthly sub 2 times in a row, the second one will fail with the error 'You have already subscribed to xxx'. I am expecting it to succeed and add an additional month to the expiry date.
Is there a way of manually renewing IAP before the expiry date?
