That was the next thing I had tried after also clearing Blokada’s cache, but with no different outcome. For obvious reasons I did not clear its storage as well.
In both cases the installer seems to happily process the new package, but then towards the very end behaves like running into some kind of version or access right conflict or such.
When I use the additionally installed APK-Installer instead of Android’s package installer, it briefly flashes “conflict with package already installed” before terminating unsuccessful.
Back on March 7th Reda replied to my initial report:
So I naturally expected a fixed package to become available soon. After a few months it eventually allowed me to update the phone, but Blokada on the tablet unexpectedly still wouldn’t cooperate.
