Lag or Issue in Unbounce Reporting?


Is there typically a lag in Unbounce reporting?  For example, at the beginning of my campaign, I see so many visitors and conversions, but my MailChimp list (the ONLY list attached to this landing page) is capturing more emails than Unbounce is showing for conversions.  Any ideas why this might be happening!?  Possibly multiple email submissions per visit?  You’d think that would IMPROVE conversion (visits to the success page) or does a single session/visit not count that?
