Hi...we've been having fairly severe sync issues today.
We first noticed them on text files that were changed on Linux. The files seem to eventually sync randomly many minutes later (if at all) to other platforms. (We're trying to limit changes to the files to only one platform now so we don't end up with orphans, but this is greatly hindering work.)
We've tried restarting the Dropbox client, having users log off and on, etc., but it appears to be a problem on the Dropbox cloud end.
