Hi Michael.
Thanks for your business and for these links.
The answer is the same as the other forum thread you linked to. That thread was also about Event Tickets Plus and was answered very recently and was answered by our Support Manager (who knows a thing or two about our products) 😉
Here is our official KB article on the general topic: Compatibility with WooCommerce Extensions
As stated in that other forum thread, we have a pretty great Refund Policy so you can buy one or many of our add-ons and thoroughly test them.
Let me know if you have any follow-up questions on this topic.
