Can’t insert a mov iPhone file recording, the forum doesn’t allow it
The correct behavior: not only should the keyboard remain open (this happens in some other excel apps), but it should retain the numeric input mode (this is another common issue for apps without own numpads, though it should be possible with 3rd party apps since, for example, PlanMaker has a special extra button that switches stock Apple keyboard into a numeric mode, so it’s possible to signal the keyboard to switch back to that mode even if it loses it after a single cell entry)
