Logitech keyboard not working with iPad 10

Logitech combo touch keyboard for iPad 10 gen.

Sometimes it only works when on screen keyboard is shown

Sometimes it cannot connect with the iPad

Sometimes the connection break halfway when I'm typing

Sometimes it is very laggy (e.g. I type "me" and it shows "meeeeeeeeeeeeeeeeeeeeee", when I delete one letter it deletes the whole sentence)

I got two replacement but the problems still exist

I also went to apple to fix the problems, but the keyboard works for a few days and the problems come back again

I desperately need help pls 😔😔
