@alexmurray @ogra I have finally tested the app on the proper Ubuntu system with the full strict support. And indeed in the strict mode the app can’t access user’s personal files.
So I updated the snapcraft.yaml to use the personal-files interface now. Although I need to be granted to use this interface, and so also to be able to auto connect when installed. Is it possible to give me access to this interface/connection and be able use auto connect?
