Same thing happening here. After 6 months of 5x ownership, suddenly I'm getting no -- none... ZERO -- "vigorous" minutes for workouts that used to get me a moderate to vigorous minute ratio of 1:10. Today's 45 minute elliptical workout had 31 minutes in zone 5 and zero vigorous minutes.
Check your HR sensor for crazing of the resin - seems to cause chaos with wrist based HR measurements - I had two weeks in the pyrenees 'scored' as easier than a stroll in the park. Garmin replaced under warranty without any quible.

I'm using a chest strap. I clean the devices regularly, as instructed. The workouts are being logged with significant time in zone 5... But, time in the higher zones is not being logged as "vigorous".
