External keyboard issues

I just bought the logitech keyboard k480 and it is not working fine on my ipad air 4. Some keys like “J”, “k”, “L”, “M”, “o”, 7, ,8, 9 are not working and is concerning me. The keyboard is working fine when I connect it my iphone and also my windows PC but somehow it’s not working on iPad. Which again brings me hope that the keyboard is fine, but there is some issue with the pairing or configuration on the ipad.

if anyone has any solutions please let me know.

Thanks!
