So old style I haven’t had this issue. Keep in mind this site is running WPML and 3 languages.
But we are trying to update the style of the calendar to the new one and have run into nothing but issues. In a development environment I tried deactivating everything and reactivating and ran into this error message when attempting to reactivate PRO.
Uncaught TypeError: Argument 1 passed to Tribe__Rewrite::remove_percent_placeholders() must be of the type array, bool given, called in /code/wp-includes/class-wp-hook.php on line 303 and defined in /code/wp-content/plugins/the-events-calendar/common/src/Tribe/Rewrite.php:177

So I had to temporarily change the Rewrite.php function at line 177 to get it so I could get it to work at least a little bit. I put it back in the attempt to let the system work as it should.
I had to do a wp-cli rewrite flush in order to get rid of a lot of the /(/?:list)/ permalink issues as doing a Settings Permalinks save did not do anything useful. I shouldn’t have to do the rewrite flush via the cli to get it to function even just this little bit.
So there are times that it doesn’t completely change all of the (/?:instances) correctly, be it page|pagina. So while pagination on the Month view works, pagination on the list view works for spanish, while i was able to get french and english (default language) working fine.
Also with this new update, we have the filters addon and its still showing the advertisement instead of allowing me to save anything on the filters tab. Checked the licensed tab and everything is green there.
