Thanks for the info @Elliot Condon. I’ll be looking forward to the article as well.
This helps a bit. I like that they have the option to rollback. I suppose the best thing to do is try to contact my clients where I’ve used ACF (pretty much every site!) with a link to your article when it’s released. I may put the ball in their court saying I can go in and fix their site with ACF Pro or they can leave as is.
Thanks again and thanks for a great plugin.
