After the latest update (or at least in the past month) some of my posts are not showing their ACF galleries in the backend. On the front end the content shows.
I can see the gallery in the backend, but the images are not populated (looks empty). If I add a new image to the gallery, it shows up fine and the front end is updated as well (including the images not seen in the gallery), but not images before the update.
No errors are showing with debug on, and no errors in the console.
Never had any issues in the past. Any idea why this would be happening now?
