Our cache is clear (WP Fastest Cache and Cloudflare). After the update to 2.3.0, the button disappeared unless the user is logged in (craftmar.com and destincondorent.com).
Thank you for advice.
Ok, solved it by excluding button from combining in cache
Hi ycolasan ! Thanks for letting us know that the issue has been resolved already! It was probably the frontend.min.js you needed to exclude from the caching plugin, right?
Hopefully you like the 2.3.0 update! If you have any feedback or more issues, let us know!
