Hi everyone,

during my runs I noticed that my heartrate was way to low for my effort and that it kept decreasing, even when I ran uphill. This is always the case in the first 5-10 minutes of the run. After that, it looks normal. The best way to fix it is to pause the activity, wait a few seconds until there is sensor data again and then resume it. HRM is a Polar H10, with my Wahoo Bolt v3 I don't have any issues during cycling, that's why I think the issue is on the Coros side.

Has anyone experienced issues with external HRMs lately? Any information helps, I want to make sure I have enough information to open a support ticket.
