Hi,
I’ve been noticing this for a few weeks, and first I though it might be something related to my setup, sadly seems to be a more widespread issue has it is happening on every site I have ACF updated to the latest.
Whenever I have a clone field, any changes I make to a post using the cloned field, nothing is saved when I hit save on the post, and upon reload the post editor gets back to the initial state, as if I hadn’t make any changes.
Anyone else experiencing this? Any known fix?
