What have you done this time? 
After the latest update as of 17.03.2021 zwift is showing me the wrong language.
My language is selected as english, and everything looks like it’s in italian.
Zwift is also loading REALLY slow compared to other sites aswell as failing to upload the file with the correct distance and elevation.
When i upload to strava it’s spot on.
You really need to implement a way to retry last upload or have zwift try the last workout again after restart, bechause i keep loosing my rides in zwift due to your incompetance.
