Hey guys, some more data:
Yesterday i installed a new site i´ve started to develope, same WP 5.0.2, same ACF 5.7.9, same Parent theme i use for all my projects…. and, when i went to some page (first edited one on fresh install) my custom fields where saved, and in fact is working.
It´s very strange, on the old websites, where i updated WP from 4.9 to 5.0, this thing about gutemberg and saving fields don´t work. But with same versions installs from zero yes they work. JS Cache problems are not the issue for sure.
I was clear? new installs works, updated ones not.
At least that´s my last experience related to this. Hope helps to find what is going on.
