I have some pages with custom apps containing simple Custom HTML. Starting today (so far as I can tell), the Custom HTML app refuses to adjust the height. No amount of dragging the gripper will make it adjust. I copied an existing page, with correctly sized Custom HTML apps, added a new Custom HTML app and pasted in the exact same HTML, and it's not allowing me to set the height. And, I can't change the height of previously created custom HTML apps (not that I want to).
Would appreciate any suggestions for getting this to work again.
