Hi All, 
I recently encountered an issue where my Synology Drive on my mobile phone is unable to sync to specific folders on my NAS.
The error message I get is attached. 
The problem is I don't recall setting anything to any folders that may block this.
Any advice is appreciated.

You will need to check the configuration options to enable two-way sync. If you don't know how to uninstall Drive and erase settings. Same with PC and mobile app. Then reinstall to get default settings that have two way sync.
