Latest updates for iPad seems to have created many issues especially for Pages

I have had problems with Pages since the last upgrade ....not sure if it is the iPad but think it is Pages. I wont open correctly, with documents on top of each other. I have to keep opening and shutting it again. Also, many times I cant type anything, or it delays the typed letters....way behind what I am typing in. Hoping for some corrections
