As soon as I logged onto Zwift yesterday, I received notifications that I had earned Achievements (Badges) for 500, 600, 700, and 800 watts. I did not earn these achievements. How do I undo or reset these errors?
At the moment there is no way to undo/remove the badges.
You can however remove your best wattage efforts (1min, 5min, and 20min) by deleting the corresponding file in \documents\zwift\cp
