Mark, a heads up. I found this on GitHub as well for ACF. https://github.com/AdvancedCustomFields/acf/issues/218
The guy’s screencast is what I’m experiencing.
Also, when both ACF PRO and Gutenberg 6.4 are active, my ACF Block with a wysiwyg field in it does not seem to initialize the tinymce editor easily when I click into it.
