I've gone through the package and tested several functions. Additionally, we have a few sites running Laravel 9 and flexible content with no issues. Everything seems to work for Laravel 9. Nothing in the upgrade guide stood out to me for being a breaking change. Laravel 8 to 9 isn't a huge shift.
PR allows people to upgrade to Laravel 9.
