No option to set Device Priority via connect web or iOS

Hi, I have added my Quatix 7 as the sole device in Garmin connect and it does not give me the option to add it as the primary wearable, as it currently shows only as primary training device. This is via connect web and iOS. 

I have had major issues so far getting the device to connect to the app, having had to reinstate software and reset the device. I am hoping there is a solution which avoids having to disconnect from the connect app to not endure this process again.

Pleased to hear any solutions
