Experiencing this issue as well.
Wordpress 5.0.2
ACF 5.7.9
Page with custom fields – when fields updated they do not save or display with updated data on front end.
Only when disabling Gutenberg and using classic editor are updates saved/changed.
Tried using Disable Gutenberg plugin targeting only pages with ACF and this did not work. It appears Gutenberg need to be completely disabled.
Any word on the 5.8.0 release that is supposedly going to fix issues like this?
