Lolo Irie, THANK YOU, THANK YOU, THANK YOU! I have tried the hack and it does resolve the ACF issue. I’m not sure if it might also mess up SNAP functionality so I have asked that dev to confirm if it is OK to use.
I still hope that either the ACF dev and/or the SNAP dev can find a more permanent solution so no hacks are required. But you helped me immensely by pointing out this hack!
