After factory reset and pairing it with my tablet, I don't get the errors anymore, the default is the same, I don't see any new apps as part of the build. I am not liking to always use the center button to go back, and the top button does not do anything, it used to launch the contacts. The below button is still mapped to LG health.
I think this is too early to be used as a daily driver, I will wait for a few weeks to allow existing 3rd party apps to be updated. For now I will go back to the current version.
