After few months of monitoring, I noticed that there's an issue with the App and recovery time https://www.garmin.com/en-US/garmin-technology/cycling-science/physiological-measurements/recovery-time/ since if I use the Garmin HRM-Dual it always shows 0 at the end of every session, doesn't matter of intensity, while the only way to get it is by using the HRM-PRO or PRO+ paired to Connect Mobile and even worse if you've some "remaining" recovery time from previous activity computed by wearable (e.g. Fenix, Forerunner, Edge devices) it will reset to 0; are you aware of it or is there a ticket already for that?
