Ok a workaround I found for the profile creation issue is that I restored a backup from the Kodi app I have installed in my Android TV with the profiles created and now switching between the profiles work. There's probably something wrong in the process of creating a new profile from this version of LE.
Also when I turn off and then back on my projector, the remote controller no longer works with LE (CEC stops working). I wanted to try to fix it using the getedid script, but the getedid command doesn't seem to exist in this LE. I am trying the latest nightly build. Is there a way I can add or run the script manually? Or is there a possibility to add the getedid command to LE? I just probably need to run the 'getedid create' command to fix this issue.
