In this update of the ACF, disappeared Page Attributes option to select models, and all pages with the options created by the ACF must be selected in the Screen Options.
I went back to the previous version and the problem does not exist.
I am also experiencing this bug, there is something wrong with the Location Rules and Screen Options. My ACF meta boxes are hidden by default when I use location rules. I am using page templates as a location rule. Using WP 4.1.1 and ACF Pro 5.2.0
2022 was a big year for Advanced Custom Fields, with more capabilities, a new generation of ACF Blocks, a refreshed UI, and a new home. Our year in review post looks at advancements we’ve made and offers a glimpse of the future. https://t.co/HahJUCcyH4
