Garmin Premium HRM - Ipad Connection

I am new to Zwift and found the connection to my 4iiii power meter easy on the Zwift Ipad App.

My issue is, I cannot connect my Garmin Premium HRM, as the app appears to not find it. I thought the HRM was both ant+ and Bluetooth, so shouldn’t be an issue.

Is this a common issue or is my understanding of the connections all wrong.

Hi John, don’t think that one has Bluetooth, i had the all singing garmin tri HRM but it didn’t have it either! had to purchase the Garmin dual HRM which has both…pretty poor when your spending £80 on a HRM and it only has ant+!
