The plugin you linked to is by a different author and it appears you need their Pro version to implement tag shortcodes.
Luckily, we’ve got you covered! If you head over to our PRO Widget Shortcodes article, we provide instructions on how to display a list of events based on tags using a shortcode. It should look something like this:
[tribe_events_list tags="your-tag-slug-here"]
Let me know how it goes and thanks for choosing PRO. Cheers!
Well, that’s embarrassing. 😉 I thought it was odd that the shortcode was different than what I remembered using in the past. Thanks for your help, as always.
