Garmin watches Not syncing with MFP

Hi all

I have just had a major email rally with Garmin regarding mt Garmin Vivofit4 not syncing with MFP
In the end they finally conceded to allow me to return my watch, but before I do that I need to know if any of you have any of these watches and cannot sync with MFP
  • Garmin vivosport Slate Large
  • Garmin vivosmart 4
  • Garmin Forerunner 30 Slate Grey
    (is this one mainly for runners)

Your input will be appreciated
