We have received recent reports from our users that there are Dropbox syncing delays/syncing issues. The patterns that we have determined seem be related to the sync between Dropbox.com to NationBuilder (not NationBuilder to Dropbox.com) present in two cases:
Case 1) The number of files synced is stuck.
Case 2) The "Last updated at" timestamp in NationBuilder is significantly different than when the file was last updated in Dropbox (X number of days difference). Thus, recent changes aren't downloading into NationBuilder.
