I can’t find the event tickets, I use to apply a lot of tickets to each event with different dates, is that still possible?
Yes, you can, although it works differently than it did in EE3.
Do you want each of the dates in the event to show up on the calendar?
You’ll likely need multiple ‘datetimes’ within the event (a new datetime for each date) and then a ticket for each of those datetimes for the user to register onto, but it depends on how you want it to work.
Do you have an example of what you are trying to set up I can view?
