yes, Tried a few times. Plus clearing the cache, rebooting. On all other androids (not 6) all is well. Strange thing is that the non official,(not Panasonic) app still sees the tv and works as it was.
Sounds weird since your Panasonic app probably only uses the build-in libraries, meaning: if the other apps work then the Panasonic should work too (unless the app is buggy and lousy programmed).
