Hallelujah! It is now working! Not quite sure exactly what I did, but it is connected somehow to the Network and permissions within.
First I created a new folder on WDMyCloud on my iPad.
I went back to the desktop, rebooted, could not SEE the new folder created. Access to any of the files on MC has never been a problem. I can see them, watch movies on the iPad from MC. I can even move folders OUT of MC; just can’t move anything in.
Altho my drive was not previously mapped, I thought I would give this a try. Can’t hurt, might help, and rac8006 had given me a new perspective. So I tried to do that, but Windows 10 would not let me. It was not showing me the contents of the drive as it had on Windows 7. (Just a WD logo, which I found strange Now it shows an icon of the files. Photo attached.) It kept telling me I needed to set permissions, so I just set everything to ALL PERMISSIONS GRANTED! (There is something very strange with this network). IT didn’t seem to be accepting that, but suddenly, voilà! I had a “tree” of the files on MC in front of me, they looked like they should (they show up as a tree), and they were accessible. And still are! AND the new folder I made on my iPad shows up!! What more could I ask?!
Thanks so much for sticking with me, Bennor, and thanks also to rac8006!! You guys really made a big difference in my sanity! Bravo!
