Hi @Randy,
Google Play handles everything to do with purchases - they take a 15-30% cut for this. All I can do is check, refund and revoke purchases. Replicating this outside Google Play would be a big undertaking and well beyond my resources.
Another user has asked about adding the Huawei Store and this is a possibility but it’s hard to justify at the moment. Maybe when we can afford to hire help.
Note, I’ve just changed the title to make it more descriptive.
Cheers, Duane.
