Oh yeah, this is a real shame about the otherwise excellent value 9th gen iPad. I’ve never liked the way it plugs into the Lightning port. At least provide a little M-F Lightning dongle so it’s flexible in case of accidents. It’s so vulnerable, especially in the context of its target audience of school students.
Apple does provide an adapter so one can charge with regular Lightning cable. Alas, I think I lost mine within 2 days of buying the AP1.
As for school students, the keynote introducing the iPad 6th gen also showcased the rugged $69 Logitech Crayon. I have one and I find it works just as well as the AP1 for note taking. Best thing for me, it works without pairing and can be used interchangeably on multiple iPads (released 2018 or newer) without skipping a beat.
