iOS App on OneDrive did not sync

Hello,
i have the iOS App version 2.6.3 installed and when i create a folder inside Cryptomator on my iPhone - i can’t see the folder on my mac and Windows PC. On the other hand, when i create a folder on Windows or Mac, i can see it in the iOS App.

Does anyone have an idea? I have a supporter licence for Mac and Windows and the Cryptomator Fullversion on iOS.

Thanks!
Alex
