I bought a brand new Air 3 in January. Sold my iPad Pro from 2016 which I regret now. The Air 3 has serious input lag and the screen won’t move or when I type something out I have to wait a minute or so for it to start acting normal again. It’s many times slow to input words from keyboard. I have tried everything. I have re-started from new. My iPad is up to date. What is wrong with it? Anyway to fix it, it is very annoying.
