This is a bug report, not a support ticket, but i didn’t find clear instructions on where to file bug reports for Event Calendar Pro.
When using the new Gutenberg editor, adding the [tribe_events] shortcode (via the shortcode block) leads to an interesting effect, which took me a while to figure out..
When the shortcode is used, your plugin loads the main theme’s stylesheet into the page. Since the Gutenberg editor is not confined to an iframe anymore (like the old TinyMCE one), it potentially breaks the whole WordPress Backend UI, because the theme’s stylesheet is overwriting a lot of WordPress one’s..
Using [tribe_events_list] does not trigger the error.
PS: A dedicated events block would be really nice, so one could avoid using the shortcode all together..
