I was so excited to use my watch today on a long run and was shocked and discouraged to see that the start up, wifi, music upload (due to wifi issues) all do not work properly. It is painful to get my brand new 265S to work properly. You're bouncing back and forth between Garmin Connect, Garmin Express, and Garmin IQ to try and accomplish anything and then run into constant error and issues. What an epic disappointment. I heard the tech was not great on Garmin devices, but WOW.
