My Forerunner 965 disconnects from my phone frequently and does not automatically reconnect

Over the past few months, my Forerunner 965 disconnects from my phone frequently and does not automatically reconnect. During the first six months I owned the watch, it would always automatically reconnect after the connection was lost. Now, it seems like I have to go through the reconnection process at least once per day. The watch's distance from the phone has not changed. Any suggestions what might be wrong and how to correct this?

Hey Garmin: Perhaps this merits a bug fix!
