iOS 9: Can't sync after update

Hi.

I hope the old times does’nt come back after syncing became finally stable in the last versions? Today i installed the new update – with special enhancements for iOS 9 – and my iPad Mini (iOS 9) is just reporting sync errors: DEVONthink can’t upload three files to my WebDAV server anymore?

Thank you and best regards,
