After updating Galaxy S4 with Kit Kat 4.4.2 no more downloads with WD My Cloud

After updating Galaxy S4 with Kit Kat 4.4.2 no more downloads with WD My Cloud. 

I can do everything else, but no downloads from the My Cloud with the My Cloud App. Nor can I write to the SD Card anymore either. I know what the problem is because Google has removed media rw away on External SD cards for third party Apps. Is this the same for the WD My Cloud App ?

Hello,

This issue is already under investigation. 

Any answer on it then ? Because I still can’t.

No answer.
