if you're still seeing warnings:
The issue is related to the use of multiple sites to host these downloads.
Have *all* of the domains been registered in webmaster console? Note that
the pattern registered by the webmaster has to be precise, similar is not
enough. Also, it looks like the authors did not file appeals for dropbox
URLs.
Can you check that you've done all of that first?
