Best,
I am having the same issue - I use Box from the Desktop regularly. I find myself recently complaining to my staff that I don't have docs that they swore they have added. It turns out the docs only stayed on Box.com but not synched to my Desktop. I did a whole troubleshoot thing, removing and reinstalling the Box desktop app. Took hours and hours to synch from Cloud. Now I have the same issue again. Most recently, I sent the file request link to an outside client to add their documents, but I didn't see the docs for days in Desktop, thinking that they hadn't add their docs. But in fact they did and I could see the document on Box.com but not on my desktop.
