A customer is reporting that they connected Dropbox last night and it has been syncing very slowly over the last 10 hours and has not finished yet. They are seeing theme files come in from NationBuilder very slowly and none of the themes have completely synced yet. The result is that the live websites that the themes are being used on look broken or are missing images.
This issue has been resolved. Please check to make sure that you are connected to the right dropbox account and have not switched accounts.
