Garmin Connect not syncing with my xert

I am unable to sync any activities from my garmin connect. I have successfully set it up to sync activities before and just recently returned to this platform. Now, it’s just not syncing past activities, and I have disconnected and reconnected my garmin connect several times. I have also reset my account several times in attempt to solve this issue. Does anyone know a fix? Or is something messed up with my account?
