GMS 2014R2 and Android 6.01


We have this installed and everything has been working. I have a Samsung
Galaxy Note 5 which just upgraded itself to Marshmellow 6.01 and since then,
my sync has not been working properly. It's intermittent at best and it
looks like there is no attempt by my device to contact the mobility server.
Restarting my device DOES seem to work. Touchdown seems to work reliably.

Anyone know of a solution or know anyone else having any issues?
