iOS 12.1.3 keyboard issues

i have installed 12.1.3 on my new 2019 iPad 12.9 inch. Started by restoring latest backup from my old 10.5 inch. Within 2 weeks the keyboard began freezing and being non responsive. I wiped it clean and started from scratch and that seemed to fix the problem. In the past week the problem has returned. The keyboard, on occasio, does not respond when typing on it. The screen freezes and it takes several seconds for it to respond once again. Mostly happens in Safari but also other apps. I have the same beta on my X and there is absolutely no problems with it.
