Hi,
After an update this morning, ACF Pro is now at 5.7.13, and I find that my custom fields I set up as relational no longer function. They will not trigger the search and the field will not accept any input.
I noticed that Gutenberg also updated, and when I switch to “classic” mode I am able to use the fields.
I know that Gutenberg has been a headache for most, but I wanted to post in hopes a quick fix could be found.
All the best.
