Hi @niccrockett
I hope you are doing well.
Even though we don’t update the “Tested up” we are committed to providing support to the latest version in all our plugins.
We are committed to doing our best to ensure that all of our products and services are compatible with the latest versions of WordPress within 24 hours of any release. We can give no guarantee that products will work with older versions of WordPress, though we will work to support backward compatibility whenever reasonably possible.

Indeed, I am using Branda along with PHP 8.1 and the WordPress Beta version and haven’t faced any issues so far, bugs are unlucky and may happen but we will fix them as soon as possible.
Best Regards
Patrick Freitas
