Okay, try the two F-Droid clients in comparison?
- https://f-droid.org/repo/org.fdroid.fdroid_1014052.apk
- https://f-droid.org/repo/ie.defo.ech_apps_1014052.apk
They’re the same version, only package name and the java security provider differ. I want to make sure if they’re using any word filter.
You may have already installed the newer version of F-Droid, which must be uninstalled first; I don’t know if F-Droid opts in to have an option to keep app data.
