Hi can anyone kindly advise I’m on the right path here. I have a Vivoactive4 watch and just bought Tacx Flow Smart. To get my watch HR accessible on Taxc app I believe I need an ANT+ USB dongle for my Mac. Is that correct? And does the Garmin ANT+ USB dongle support Vivoactive4 since not listed in the supported devices? Or do I need some other setup? Thanks in advance.
