Nevermind, I figured it out. I was overlooking something very obvious, I didn’t have a calendar selected in the Reservations List View.
Just a quick suggestion:
Perhaps the default could be “All Calendars” and show the reservations from all of them, instead of “Select Calendar” showing none, that way users could easily see if any reservations have come in on any of their calendars.
Anyway, thanks for the plugin!
