Hi Donaz,
Welcome to the Cubasis forum.
Thanks for your message, which unfortunately is not easy to follow/understand (as it seems to include many purchases on top of each another).
Below I’ve tried to answer a few of your questions and sharing facts about Cubasis 3 and Cubasis LE 3:
Cubasis LE 3
Cubasis LE 3 runs in a free demo mode, unless unlocked via a compatible/bundled audio device. Once Cubasis LE 3 is unlocked, users are free to purchase optional in-app purchases, such as the Full Feature Set IAP, which updates Cubasis LE 3 with the same features of Cubasis 3 at a reduced price, while leaving the app name and icon remain unchanged (due to technical limitations).
In-App Purchases Transfer
When we’ve released Cubasis 3, we’ve included the option to freely transfer existing Cubasis 2 instrument and effect plug-in in-app purchases to Cubasis 3, as described in the following article (which has been released in Dec `19): How to transfer Cubasis 2 in-app purchases to Cubasis 3
Refunding app purchases
Cubasis for iOS is distributed via the Apple App Store. Here, it is important to know that only Apple is able to refund app purchases. As a first step, I strongly suggest to get in touch with someone at the App Store asap, trying to explain the issue and to discuss the feasible options to receive refunds for your doubled app and/or in-app-purchases.
Hope that helps,
Lars
