I am building a plugin, which relies heavily on Meta Box -plugin. Everything works fine, except when using classic editor, ie. with Classic Editor or WP Bakery plugins. Then the changes to the fields are not saved.

I was able to track the issue RW_Meta_Box class save_post() function does not fire for some reason when clicking the "Update" button on classic editor.

I tried to add action to proper hook for fixing the issue, but was not able to.

Is there a solid fix for this issue?
