Down button is getting into a squished/stuck state constantly

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.
