Why submissions are not immediately sent via email?

Unless the DropBox was just set back up by someone at JotForm when I look it says it IS configured. I have submitted 7 submission forms since 4pm. They eventually came through although not to Dropbox and they each took 15 to 20 minutes each to pop in to email.

I can see you have already opened another thread about the same issue, you have already received a reply on this link too: https://www.jotform.com/answers/1055178 

Please, check that reply and follow up on that thread, this will help us to assist you better. 

Thanks.
