the0815 I try to get all my apps (anonymously) from Aurora Store. However, certain apps only work when downloaded through the official Play Store, so I was forced to download it back then.
Recently the Play Store (or is it the app itself?) suddenly started forcing me, to override the version of an app which was originally downloaded from Aurora and which worked perfectly fine for months/years, with a version from Play Store:
I would recommend that you put your FOSS apps and apps without network connection in the main space and the apps that require Google Play Services in the private space, if you have more Google Play Apps then you can also reverse this.
This would fix your problem with Google Store and also blocking any Inter Process Communication in generell.
