I have a Cirqa and the Garmin Connect website shows it as the Primary Wearable and the Primary Training Device. I can't see any way in the website or app to set my HRM 600 to the Primary Training Device instead. I've checked the manual and troubleshooting and the option doesn't appear where it is supposed to. I'm wondering if this means the Cirqa doesn't support this as I'm assuming the HRM 600 must. Any ideas?
The other possibility is that it is a bug in Connect's interaction with Cirqa, as there appears to be a lot of those!
