I have a similar issue. The prior free version 4.4.12 stored the Date Time value as a timestamp by default. I’ve found that the free 5.7.6 version stores the Date Time value as YYYY-MM-DD HH:MM:SS, with no option to store it as a timestamp. The database update that went along with 5.7.6 did not change the old Date Time values to the new format. After a couple of days of use, we discovered that the part of our website that depends on Date Time was broken because the database had mixed format values. I was forced to revert to a site backup done before the plugin update, losing a couple of days of work.
I posted a support ticket to ACF but have not received a response. I’m sure they’re overloaded with support issues this week.
