Since a couple of days ago (~2 weeks) my HRM Pro Plus has stop syncing heart rate with Garmin Connect even if the device appears with the green dot under Garmin Connect. Before I use to have HR graphs for my day no matter if I tracked my actives with devices (Zwift for Virtual Cycling or Apple Watch for running). Now, it's not longer the case.
Screenshot from a couple of days ago when everything worked fined:
Zwift ride
Apple Watch run:
Now, the graph looks like this:
Anyone know what might be going on ?
I've tried re-pairing my HRM Pro Plus to my iPhone, force resetting (by removing the battery for more than 30 secs), the reverse polarity trick etc
I've the version 4.66 of the connect app but the issue was also present in the 4.65. My iPhone is running iOS 16.4.1
