Just this past week, I've started to notice my down button on my Forerunner 945 LTE getting into a squished/stuck state. It's very frustrating. Has anyone else had this problem with their watch? I keep my watch very clean and primarily use it for running. In fact it's never dirty at all. So I can't see how this could be environment related. On a new watch like this, I'm really disappointed. I just emailed Garmin Support.
