Thank you @elliot We’re also having the same issue with the classic editor, will submit the bug report accordingly, thank you.
Hi @elliot,
We’re still having the same issue, not only with draft preview, but also with published posts when set to private.
ACF version: 5.8.9
WordPress version: 5.4
Is there a quick fix for that? also, happy to share more information as needed, to help resolving that issue, it sounds like a common glitch, so would be very helpful to address it as soon as you get a chance, thank you for your support.
All best,
MADEO Dev
