After upgrade to Acorn 3 I tried to activate Ignition:
$ composer require spatie/laravel-ignition --dev
$ wp acorn optimize:clear
With no errors in the terminal. Now, ignition shows its page with no CSS:
PHP 8.1.18
Acorn 3.2.0 (Laravel 9.52.7)
Are you logged in? Admin bar seems to mess ignition up for me.
