Magic Keyboard the cursor keeps jumping around

I have an I pad air gen5. I have with multiple Magic keyboards and both have done the same. You are typing the cursor jumps. Literally makes the IPad non functioning. Sadly the IPad is only good for entertainment and my needs are more business. Are their other non keyboards that work?. I wish that Apple would make an IPad for business. The surface was business but not good for entertainment. I can not carry both. Just the write this comment. I six issues of the cursor jumping. Thanks. Chuck
