@MMRIZE Sorry, I am also trying to set up a Goolge Keep module, which is not working yet. It looks like it was blocking the calendar view.
I removed the Google Keep for now, and I can see my calendars.

Hi All,
I just installed MMM-CalendarExt2, and going through the initial setup. So far it is a sinlge Google Calendar URL, a simple today view and a scene that contains all views.
But when I start the MM, nothing happens. Nothing is being displayed, but I am not seeing any error messages either.
I have the standard calendar on the screen as well which shows my upcoming events using the same Google Calendar URL.
I guess having standard and Ext2 in the config file is not a problem.

What did I miss?
