Works as advertised – CloudExplorer for Cloud Drive Review

I'm not sure what the other review is talking about. The pro upgrade states very clearly that it allows you to import and export to any service supporting storage extensions. It DOESN'T say it provides a storage extension for Amazon Cloud Drive that would show up in apps like Pages. That would be a nice feature, though, or at lease offer something in the share sheet. In the end, read before you buy.
