I’m just starting to use the Gutenberg editor for all my ACF needs now. However, after registering the block it can be selected in the ACF field creator under blocks > Test & assigned a field. However, it’s not displaying as an option with the Gutenberg blocks drop-down on a page?
I have similar problem with registering blocks. I have also WP Version: 5.3.2
and ACF Pro Version: 5.8.7.
It doesn’t work on server with PHP 5.6, but it works on another server with PHP 7.x. Can be reason?
