I was essentially trying to use the hook to run code that would update two fields (a time and a date field, that post mentions a datetime field but I ended up using a different method in the end).
In 2.3.2, when I changed from invisible → visible, the hook would fire as expected and my code would run. But in 2.4.0, it doesn’t do anything.
Sure, I can create a GitHub issue with the same information, no problem.
EDIT: panel.page.sort not firing as expected · Issue #952 · getkirby-v2/panel · GitHub Issue created.
