Here’s an example of the different save formats in the DB (with ACF and with the option from the theme): https://imgur.com/a/epHe0TS
The problem is that there are also some plugins who belongs to the theme, which uses this format. And with theme updates (it’s often) they will also be overwritten, I use already a child theme.
So there’s no possibility (in the scripts of ACF) to change the date-format in Y-m-d?
