Can’t Verify Dropbox

Trying to add Dropbox as a remote storage option, but I get the message “Dropbox connection error: Could not write data” in the plugin when I try to verify.

Have created a full access App in my Dropbox account and copied the key and secret over, but it doesn’t seem to want to work.

I tried another backup plugin that was able to send data to Dropbox, so I know it’s possible!
