hrm-dual is not in the selection of garmin connect app. according to galaxus, however, the hrm-dual is compatible with the fenix 6 pro. in the app selection of garmin, however, i only have hrm-pro and hrm-pro plus. my iphone recognises the hrm-dual and has established a bluetooth connection. is there any way that the hrm-dual can still (and according to galaxus) work with the fenix 6 pro? otherwise the information is incorrect and the product is unusable.
