How to transfer Cubasis LE 2 instrument and effect plug-in in-app purchases

This is not working for me. I am on an iPad Pro with IOS 13.4. I have Cubasis 2 v 2.8.2 with many plugins purchased. I also just purchased Cubasis 3.0.2 on the app store.

Upon opening Cubasis 2 I have no option to “Transfer” any purchases, and upon opening Cubasis 3.0.2 When I go to the in-app Shop and attempt to restore purchases it tells me there is nothing to restore under my account.

How can this be resolved?
