My garmin vivoactive 4 always tracked sleep pretty well. I stopped wearing it at night for a while and now I'm wearing it again it isn't tracking my sleep. I'm also noting that last night it shows as no heart rate either when n the watch was worn all night. Any thoughts or help much appreciated. On a side note, a bike ride of mine I did the other day shows in connect but it wouldn't upload to Strava. Again, never had this issue before but again I'm now having issues. Beginning to get fed up with garmin and feels too unreliable.
