Hi @refreshingdesign
This is something I am yet to test with ACF.
Perhaps you could test the waters on this one?
I believe there is some sort of ‘satellite’ or ‘broadcast’ plugin which you can use to send the data between sites.
Also, there is the export to PHP feature within ACF which you can then use to register fields via code. I’m sure you could find a way for the individual sites to all load from the same file!
Good luck
