PDFs not available for download – Mendeley (PDF Reader) Review

Spent a whole day adding and uploading my pdf literature library to my Mendeley library. Installed this app and signed in and only a handful of random papers were available for download. Went back to my desktop Mendeley library to find all the pdf uploads were missing. Not sure how they all got removed, but perhaps from syncing with my iOS Mendeley app. Very frustrated with this at the moment, thinking I should just stick with organizing my pdf lit library manually.
