Logs out when I press ride

I 've had no problem with zwift. I haven’t used it for over 4 months and tried to ride today. I’m connected vis iPhone and Tacx. All is well until I press “ride”, then zwift logs out. I’ve uninstalled and reinstalled. No change

Is this the same issue: https://forums.zwift.com/t/oct-16-update-crash-ios-13-1-2

Yes. Thank you Paul!
