They are indeed still relevant and each seems to behave as expected when I test them. Can you confirm where you added the code in question?
Could you also provide a link to a live example of a single event page containing tickets, in case that provides any clues (unfortunately I found I was unable to use the URL provided when you opened this topic)?
Thanks for the quick reply. I ignored the part that stated to put the code in the fucntion.php file and instead placed the code in a plugin I often use “Code Snippets” which failed to properly load the snippet.
After placing the code into function.php file I am know all set.
