[Owncloud] External Storage :: not working

[Adrian Sevcenco]

Hi guys! First of all let me congratulate you for the amazing job that
you do with the OwnCloud software!!

Second things is a bit of complaint : i try to use the External Storage
and it does not work at all for both dropbox and google drive .. is it a
known problem or i have to do some extra steps to enable this?

Thanks a lot!
Adrian
