New thread for latest GCM.
After installing, everything works initially. But give it a few hours and you will once again get sync errors, and also notice that your weather is stuck. No updates to it or the temperature.
I went through all the steps needed to install this new update.
Uninstalled GCM
Forgot Watch in Bluetooth
Rebooted phone and watch.
Installed everything again.
Initially you will think it works, but just give it time. Same old problems, nothing fixed. Honestly, do they even test this stuff.
I'm back to doing a WiFi sync to get things back in order.
