Garmin HMR dual no signal

I have this problem , i don’t want to do, please help me


Make sure it hasn’t connected to another bluetooth device (like phone) as this will be what you see on screen.

Also make sure your battery is good.

Other suggestions include removing battery for 5 minutes. Force restart of zwift app and or iPad. Put battery back in.

It’s a common error/bug. Not sure there is a fix that always works.
