Thank goodness for that, I though I was going mad. Exactly the same issue. All dates presented on front end a day behind but OK in back-end. Upgraded ACF and WordPress to latest versions so I don’t know which has caused this problem.
This is a football results website so is date crucial. Added dates to day and they are OK, it seems to be dates that were created prior to the upgrades. Re-saving doesn’t seem to solve it.
