It would be really nice if the Mac (and, I assume, the PC) version of Garmin connect would sync software versions with the online information.
I updated my Vivoactive 4 with the latest version of the firmware a few days ago ... the GC online says the VA4 is up to date, but GC on my Mac says there is an update needed.
The update won't go away until I sync the VA4 using USB.
