Bluetooth Services Limit?

I added Heart Rate Battery level to my Battery field. I used BT for that one, since Garmin doesn't provide a high level interface and therefore when the native device pairs with the HR Strap via ANT, CIQ can't see it. So the field opens BT channels.

AI tells me there is a limit of 3 BT services that can be open. It isn't clear if the hard limit of 3 is on a per CIQ app level, or across the entire CIQ ecosystem (like the FIT field limit is and crashes CIQ apps without a way to detect/prevent). Anyone know?
