Category Enforcement turned off for Zwift Race Like a Champ?r

In my latest race today, Race like a Champ in Yorkshire, it seems a few B riders made the grade for Cat C and rode like B riders. Is Category enforcement turned on? I know it says it is and I couldn’t select Cat D.
And if a rider does ride over limits, is the cone system not used anymore?

Thanks for clarifying.

If a racer haven’t ridden for 60 days then there category will be lower, the good news is it will only take one race to set them back in B

Coning still exists when you have superhuman values.
