I’m looking for a similar feature. Basically, I want all events submitted across all sites to be able to be shown on all sites’ calendars. I have the global tables set up, and the main site is currently displaying all events from all sites. How do I achieve this same approach on my sub sites, rather than just show their own events? I’ve tried the shortcode you suggested above, but it doesn’t seem to be doing what I need it to do.
Thanks!
