I received my P9P and went ahead to setup without GOS... (due to my watch coming - and requiring a stock wearos/android to get the watch setup prior to install GOS on my P9P)
One thing I looked to do immediately was to disable network access for many google apps.
Was really surprised to find out that the option to remove network/location permissions IS NOT THERE! (not that I could find).....
... just a huge slap to the side of the head why I need to get back on GOS as soon as I can.
(note: playing around with Netguard a bit to see if that helps)...
