Can't connect Zwift app

I’m new on Zwift. I have a monitor from Vortec with Bluetooth. I’m not able to pair the monitor with Zwift cycling app. Do y have any idea? (I have a Samsung S20 smartphone)

Hi, do you mean heart rate monitor? If so, is there a possibility that it’s already paired with another app or device?

With Bluetooth devices can only be connected to one device at a time.
