I'm currently using an iOS and was previously downloading a map from Marketplace. I completed my purchase and my screen told me that the purchase was "in progress" so I thought that everything was fine. A few days went by like that and it remained the same and I have no clue what to do.
Resolving as a duplicate of MCPE-49997 - you might like to read through the workaround the user found there for the purchase. For any further issues with your account, please contact
Mojang Customer Support directly who should be able to advise you further.
