Phantom activity on and zwift companion app

30/03/2020 around 9PM I had a ride on zwift which dit not sync to my zwift and strava account. The zwift app remained open for a good ten minutes (probably trying to upload the activity) but then it gave up, I had a solid internet connection at the time and did not kill the application manually, it killed itself.

On the activity appears in my feed but when I try and open it an infinite loading screen appears. The error I get in the console is: 400 (Bad Request)

On the zwift companion app I get the error “Activity detail could not be loaded”
Presumably the zwift companion app just handles the json not being on AWS s3 slightly better.
