Thank you everyone for reporting this bug. We are working to correct this as soon as possible.
WORKAROUND In the meantime - please try this workaround if you use Zwift on an iOS / AppleTV / Android.
- In Android / iOS / Apple TV: change language preference in the bottom right from Chinese to a different language.
- Log in to Zwift and user a different language for now.
This workaround is not possible on PC / macOS. We ask for your patience while we work on a patch that fixes this issue for all OS platforms.
