Pro is not showing after I paid

Open Profile › Restore purchases while signed in to the same Google account you paid with. If a payment is still pending, Pro opens by itself when it clears.

Cancel or change Pro

Pro is a Google Play subscription. Cancel it in the Play Store app under Payments and subscriptions › Subscriptions. It stays on until the end of the period you paid for. Refunds follow Google Play’s policy.

A new phone

There is no account. Save a backup file from Profile and restore it on the new phone, or let Android’s own backup bring your progress across. Pro comes back with Restore purchases.
