Purchase Cryptomator issue

I have purchased Cryptomator and use on iPhone for several months, now running on iOS 14 and found I need to purchase? Were using the same email and other purchase was fine except Cryptomator is missing in my history of purchase.

We don’t have much control over the purchasing system behind the App Store. You might have to contact Apple about it. From our end, nothing has changed in regards to “how to purchase Cryptomator for iOS”.

Thanks will check with Apple.
