Cannot Copy to NAS

Have win10 and now cannot copy to mycloudmirror with windows file explorer. Can access the NAS but cannot copy. Could having files also copied to MS Onedrive be impacting? Appreciate any help.

Hello,

Please refer to the following KBA article: My Cloud OS 5: Certain Folders are not Copied to My Cloud Device

This is the OS3 forum. Not sure the OS5 link is relevant(?)
