I noticed that you included bluez in the list of plugs. When I don’t have bluez in the list of plugs, I get an AppArmor deny on bluez, but it doesn’t seem to negatively affect the application. I asked mborzecki about it and he said not to add bluez to the list of plugs.
Not a problem, I just thought I’d mention it since I was looking at Cumulonimbus to see if I missed anything in my Snap.
