I regularly host files and folders in my Dropbox that are shared with clients. Since October 1st these share links do not work. Dropbox will generate a share link but when my client clicks on it they receive an error 400 screen. Sometimes I can go back a day or so later to send another share link to the same folder and that one will work. I've been having to revert to sending folders using WeTransfer instead. Please let me know what I can do to fix the issue on my end or if there's a timeframe for this issue to be taken care of.
