Why are the reminders showing incorrect invoice due dates?

Why are the reminders showing incorrect invoice due dates?

Satago will mirror invoice due dates from your connected accounting package. If you find that an invoice due date is incorrect in Satago, please check the invoice due date within your accounting package, as it is most likely incorrect there and should be corrected - in turn the due date will be corrected in Satago on the next data sync.

How often does my data sync with Satago?
