Hi there, andersthorborg,
Are you maintaining the plugin still? I’ve seen some users mentioning the plugin not working with the latest WordPress or ACF. I’m not running into issues myself with my custom theme, but I do know that Gutenberg will most likely produce with older plugins.
Thanks for your contributions!
Thanks for the update, Dalton!
I can also confirm having issues with this bug. My situation is exactly the same as what Garyrae describes. Changing template page to something else, then back makes the fields appear, but upon entering the page the fields are currently not appearing.
Thanks for all your help!
