I think i have to add that i have write permissions with the unRAID server.   The problem is the share for Windows computers. I can read the share mount of Dropbox /mnt/user/unRAIDand/Dropbox and copy from it. I can write to the unRAID share /mnt/user/unRAID where the Drobox share is mounted.   Reverting back to 6.9.2 and i can read/write to /mnt/user/unRAIDand/Dropbox just fine.
