I have two websites now that are presenting the same issue.
I am attempting to delete a repeater row programmatically, using the delete_row() function. This works in so far as I can see the row has been deleted in the CMS, but I have to update the post for this action to save.
Both sites are running the latest versions of ACF Pro (5.9.3) and WordPress (5.5.3), one is using the classis editor plugin, one uses Gutenberg.
Can anyone advise how I might be able to force a save on this post after a delete_row() operation?
