I have had the Garmin Vivosmart for about 6 weeks. I have had lots of trouble getting the heart rate monitor to work. I still have never got it working. While trying to follow some suggestions from other posts, I have tried to log in Garmin Express for the first time and get the message that there is a problem with the servers. I have had this for 2 days. I have not yet been able to use it once. Any suggestions would be greatly appreciated as I really want to start using this device to its full potential. Thanks.
