how much is the data update time of a connection with adform using supermetric,
because i don't refresh anything metric in 3 hours after setting a dashboard
If I understand your question correctly - the data pulled by Supermetrics only refreshes when you manually tell it to or if you have an automatic scheduled refresh set up (see Can I schedule my reports to be refreshed or emailed at specific intervals? for more info on that feature). It otherwise does not update the data on it's own.
If this is not what you meant though, please clarify your question and we can assist further.
