I use a Fenix 3 running the latest firmware paired with a Moto X 2nd generation running Marshmallow.
The combination has always worked very well. However, over the last week, while syncing and widgets still work fine, smart notifications have stopped coming through. I got it to start once by reinstalling GCM and restarting both watch and phone, but two hours later it stopped working again and there has not been a single notification in the last two days. This coincides with the updates to 3.3.1 (working rarely) and 3.3.2 (failing completely). I have hard reset the F3 and all that achieved was duplicating half of my activities in the last month on Connect.
Anybody else seeing similar issues, on the F3 or other platforms?
