When I start a cycling activity on my Garmin Edge 1040 and receive heart rate data via HR broadcasting from my Garmin Fenix 8, the watch/Garmin Connect registers this as a stress level of 100% for a few seconds before returning to normal. This happens every time HR is sent from the watch to the bike computer via HR broadcasting. This also occurred with my previous Epix (Gen 2) watch.
How to fix this issue?
