Hi @sergiozambrano
Your issue isn’t with ACF per se. Your issue is that you’re loading so many editors that it’s not viable for the browser to instantiate all of them and you get timed out (is my guess, or it takes a long time).
Rather than trying to accommodate for such a setup you should rethink your architecture. I would instead create a custom post type (you can use plugins for this) where each post will hold one presentation as either an ACF field or you could use the default editor.
Even if it did take a few minutes to do a “fix” for this a plugin of this size can’t just do a minor not critical change and push out a whole new version. People would go crazy over new versions being released constantly 🙂
