      Hi,
      I use UBports RC release with my pixel3a and when I start application with a custom WebEngineProfile as uteezer https://github.com/Tafitson/uteezer/blob/main/app/Main.qml apparmor denied access.

      The policy https://github.com/Tafitson/uteezer/blob/main/uteezer.apparmor seems good and I've this problem with all applications started with a custom custom WebEngineProfile.
      If someone have an idea 😁
