When editing a custom post type page with ACF Gutenberg blocks, the acf/ajax/fetch-block call hangs and times out several times. After 30s the blocks load but everything is slow or unresponsive before.
I am only facing this issue at live server and not in wamp localhost. Actually the ACF blocks are using admin-ajax.js to load preview html as well as edit. This is causing more trouble. For every block preview (for fresh load or in editing), there is a request. I don’t know if this will be solved by ACF or not…
However, the native WP blocks are not using admin-ajax.js rather using react.js
