I have a Garmin 945 with an HRM-Pro using a Stryd foot pod. I was running using the virtual run mode connected to Zwift using the companion application which I do all the time and sadly my Internet connection was disrupted. When that happened I could see the connection failure within Zwift, but I continued to run on my treadmill and all the information to my 945 was accurate (Speed, heart rate etc...), but when the connection restored my heart rate was stuck at 152 bpm even though I could see that it was not at 152. There appears to be a bug between Garmin and Zwift where it does not re-establish the heart rate properly when the Internet connection is disrupted. I'm positive that Zwift has a way you are supposed to verify the connection stays up and if it goes down, how you are to re-establish connectivity which is where the bug is. Please let me know if this is a known issue.
