Google recently replaced their messaging app Hangouts with a new app called Chat. I am getting the notifications from Chat app to my Garmin Device. For some reason the notification always contains also my email address (as the recipient). This is obviously quite unnecessary information (I know that I'm the recipient) and including this info is limiting the amount of the actual message content shown on the limited screen real estate on my watch. I trust Garmin could parse the notification content on their end before showing the notification in the watch. Worth noting is that I don't see this email information getting included in my Android phone notification list for Chat app.
