in iOS15 iPad the behaviour of the shortcuts bar with an external keyboard (bluetooth Apple) is erratic. First of all, the bar sometimes appears, and sometimes not. Then in iOS, when the bar is minimised (or does not appear for some reason), a button in the lower right should appear to maximise it again; but this never happens with Textastic. I need quite often to access to the shortcuts bar to switch from the external keyboard to the on-screen keyboard to use my math symbols keyboard.
