i've got a Garmin Instinct, it's not one of the models that needs the update for this issue but an unrelated update went out mid December for it , its supposed to auto update via Garmin Connect via Bluetooth, but didnt, i had to manually updated it with garmin express, connecting the watch to my laptop with the USB cable

Devices confirmed to have GPS accuracy problems (by users)
This also appears to cover a wide range of devices. So far I have seen:

Garmin Fenix 6 Pro (me) and other Fenix 6 series watches
Garmin Forerunner 945 (a forum thread dedicated to it)
Garmin Forerunner 245M & 245
Forerunner 45 (multiple forum posts)
Vivoactive 4
Forerunner 645/645 M
This appears to affect all device using the Sony GPS chipset so it can also include

Coros GPS watches
Polar Vantage V/M/V2, Grit X, Ignite
Suunto 5 & Suunto 9
