Hello,
Thank you for your feedback!
WebDAV support may have some problems. To further investigate, we hope you can share with us the "Info" level logs.
You just need to click SKYBOX's Global Settings, change the Logging Levels to "Info", reproduce the issue, then click the BUG icon in the upper-right corner of Global Settings, and send us a bug report attached with logs(tick the "upload logs" box). Thank you!
