I loaded a custom workout today as I have many times, and during the first few seconds of the workout everything seemed normal (the program’s intervals at the built watts, listed at the top left of the screen), and then suddenly my entire program flatlined to 5 watts. Every interval was at 5 watts.
Looking through all of my custom workouts, I noticed they were all flatlined at 5 watts.
My Zwift has been updated to the latest release.
Strangely as well, my avatar is stuck riding in a sprint posture, also as of today.
Check your FTP. Maybe it is set super low.
Thank you!! It must have been reset somehow! How strange! Problem solved. Many many thanks
