Hey Erin , first of all, welcome to the Buttonizer Community! 🥳
About using the standalone on WordPress
The standalone PRO version is fully compatible with WordPress! We'll release an update shortly which will make the integration easier with our WordPress plugin. This update is currently planned for February.
Fortunately, when going PRO with the standalone version, you do not need to download or change any other files on your site. That's being done on our side automatically using the snippet 🙂
I've investigated your site and saw everything was integrated correctly. However, it appears that the page rule you have set up was not working as it should.
After some more investigating, I've found a bug in our end which caused the rule to not trigger. We've deployed an update on our server and I have confirmed your button is now visible on the correct page on your site! 🎉
The buttons are now also visible in the editor if you go to the page with that URL (they're not shown on the home page).
Hope this helps and explains all. If you are experiencing any more issues, make sure to let us know!
