Trying to install apps from the Nethunter Store and I get a message saying:

Error installing Hacker's Keyboard

The privileged permissions have not been granted to the extension! Please create a bug report!

Running a fresh install of nethunter-bullhead-oreo-kalifs-full-2019.3.zip on a Nexus 5X.

All instructions I can find are about flashing the privileged extension from F-Droid. It is installed but I also tried installing it through Magisk and also flashing it through TWRP with no luck.

Any thoughts?
