On or after July 12 the pro companion app will be removed from the Play store by Google because it uses the permission
QUERY_ALL_PACKAGES. I am not going to try to provide a justification for this permission because Google will most likely reject it anyway because an app is not allowed to directly or indirectly have an effect on other apps, which is the whole purpose of XPrivacyLua.
This means that the pro companion app will only be available outside of the Play store after July 12. Pro feature purchases will keep being recognized as long as the app is kept instalmled, but it won't be possible to install the app again after it has been removed from the Play store by Google.
Note that it is not allowed to use Play store purchases without/outside of the Play store. So, I can't transfer or exchange a Play store purchase for anything else because it would mean violating the agreement I have with Google as a developer, which could have consequences for the other apps published in the Play store (FairEmail and NetGuard).
