Garmin rolled out GCM 3.22 for Windows Phone today. I am still testing but started to having issues with notifications again. Will report about Bluetooth stability and battery drain in some time.
I am facing issues with notifications. Sometimes they hit the watch but then suddenly not any more. Also I am not receiving notifications for Skype at all. I have also removed the setting to allow GCM run in background always.
Concerning weather widget: on the first page it shows the current weather situation, that also works on my watch. But when I enter the widget (select button) I only see "waiting for data". Is anybody else able to see something different?
