I've put a PDF in the Cloud section, so that everything I did would be synchronized everywhere. I have read 40 pages and highlighted everything I wanted, only to discover later that some highlights were saved and others did not. I have to read 20+ pages all over again.
If I am in the cloud section and I highlight something, it takes ages for the "saving of x.pdf file completed" message to appear, even for highlighting one single word, and sometimes it doesn't appear at all!
Instead when you use a PDF that you shared with yourself there is ALWAYS this bar showing the synchronization status (the cloud with the green dot). When I am in this mode (using a shared file), the syncronization is istantaneous and you see it so that you are sure that everything is saved, as it should be!
Why isn't that the case for all documents in the "Cloud" section? Why? I wasted hours for nothing.
This bar should be always present in all the documents in the cloud section.
