Yes, that helps. Wondering what was the issue, priority? While I was trying with
acf/load_value before the most what I got in dump was array of only attachments IDs from gallery, so I guess that it was the main reason for those filters to for example add more images to gallery by code, and then other hooks will generate arrays of their data later on?
Do ACF have some more detailed documentation somewhere?
Thank you 🙂
