Logitech Pebble i345 Bluetooth mouse won’t work with iPad 6gen

The Logitech Pebble mouse is the 3rd Bluetooth mouse that I’ve purchased and tried with my iPad that does not work. I don’t think it’s the mouse, somethings not working with my iPad.

All of the mice? mouse pair and connect, but no cursor appears.

I have turned on Assistive touch.

As I understand it, all of these three devices that I bought were designed for the iPad, so why don’t they work?

I bought a Bluetooth keyboard that works just fine….

I have a 6th gen iPad that I just took out of the box a week ago.

Any advice?
