Nope, I don't have those errors..Will try that, thanks. Are you having random "google play services stopped working" errors? Maybe this also causes the PGO error in my case. And do you know from which stock firmware you had before flashing RR (dunno if that makes a difference)?
I had the latest official European Marshmellow release, can't remember the version number sorry.
Adopted storage seems to cause some instability if using the developer option "allow transfer of all apps to SD".. I had to move Chrome and Hangouts back to internal storage, seems to work now. If you are using adopted, check if Google Play services are in internal or SD?
