In reply to Nick.

Oh Nick, I appreciate the constructive feedback,.and I have had my share of GitHub issues waiting for attention. It is a huge project, indeed. I was just hoping to get some information from you "ACF Pro will get a nasty surprise with WP 6.5, unless this bug is fixed"
Given that Beta 3 is next week and you referred to 'this bug' that there is already something filed somewhere to get the release lead take look at it during triage.
