Shuji at Zwift HQ here. I see your multiple logins recorded on our sever on January 26. All of those logins were on an older (problematic) game version running on iPad.
The final login was from a Windows machine running the latest version 1.0.61590. Did this error also happen on the Windows machine?
I’m curious what happened after you updated iOS + run the latest iOS version of Zwift. Apple released a critical iOS security patch yesterday.
If the iOS 14.4 patch is messing with Zwift, we’d obviously like to verify this is happening from more members.
