Anybody have issues with track mode workout with autolap and recovery time is messed up? Also HR seems funky

Yes - going straight into next interval with no recovery step.. distance measurement also incorrect.

Yes, me and some others had similar issues: https://forums.garmin.com/sports-fitness/running-multisport/f/forerunner-955-series/323476/track-run-workout-bug-and-total-distance-off

Have you contacted Garmin support already? 

How do you contact Garmin support? I'm not familiar with the process. And what would come out of it? Thanks

I went here: https://support.garmin.com/de-DE/?productID=777730&tab=topics&topicTag=region_training

and started a support-chat with a Garmin employee (Link at the bottom of the site). 

I think that problems like these get fixed faster, the more people reach out to Garmin directly. At least that is what I’m hoping for
