So you guys have 2 versions
Response from developer
Hi and thank you for your review. Yes, that's correct. This paid version is a legacy product, but it offers many advantages over the free version. For example, it has no ads and no tracking, so fewer updates are needed. If it were possible to migrate the apps to continue recognizing buyers within the app, I would have done it already. Until then, both apps will remain available, and I hope you enjoy them.
