Sorry for the delay, @baypromtoeam — Jaime is out this week and we weren’t able to get back to you before now.
Looking at your system information (you may by now have reconfigured things, however) it looks like within the Events ‣ Settings ‣ Imports screen you have configured an import date range limit of 72hrs, which is pretty conservative.
Is that still in place and could you try limiting by the number of events instead, setting it to something suitably high (perhaps 300 to start)?
Let me know if that helps with this 🙂
