I was creating an expense report today.  The receipts had been sent to me as a pdf and were in my email.  When I went to Drag & Drop the receipts into the line, I had to do it twice.  The first time, I'd drag & drop, I'd get a message that it was uploading, but nothing happened.  So, I'd wait a minute and then do it again.  The second time, I'd get the uploading message and then another message that shortly after and the receipt would be there.  This happened with 4 expenses.  Is there a time delay on the drag & drop or is it just being "glitchy"?
