Garmin HRM no signal..!

My Bluetooth Garmin HRM has been working fine with Zwift for weeks but now connects with my iPhone 11 pro only to immediately inform me “no signal” and failing to produce heart rate readings.

Any ideas why?

Same here

I’ve got the same issue

Same here! Brand new HRM Dual, used once, still connects to phone and watch just not in zwift.
