Zwift Workouts don't show lately

Two weeks???
That’s the case since april 2021:

Recent issue syncing

It seems that this might be an intentional change by Garmin. My activities are working because they are recorded on a Garmin device and uploaded using the Garmin Connect app. I had a look at @Theo_Bromine’s data and his missing activities are from Zwift and @Justin_Hopkins has missing rides from Trainer Road. I found this on a Garmin developer support forum: Fri, 04/02/2021 - 10:48 “Activity File 3rd party upload file update” - Disappointed We and the users are really disappointed about this…

Garmin Connect no longer transfers workouts that are not done on a Garmin unit.
