@seriphyn Just trying out your solution, but it doesn’t appear to be working… Do you know if this is still a viable solution with the latest ACF and WordPress? Thanks!
Edit – I’ve found it is working for Publish/Update – but not Save Draft. Is there a different hook available for saving drafts?
It seems this is the expected behaviour for ACF, so it does not validate drafts regardless. Thanks for posting a solution, much appreciated.
