There have been some reports of Zwift not saving rides to your folder on Windows 10. This is due to a recent Windows 10 update that added the Controlled Folder Access security option by default. This option blocks write access for certain applications that may be seen as malicious unless you give those applications permission.
Workaround: If you run into this issue you can add ZwiftApp.exe as an exception to your Windows Defender’s Controlled Folder Access settings.
