I also use ipad exclusively and not having problems. Yesterday, I was having issues on another matter but I think it was related to being kicked out of signed in status and having to login number of times.
Were you doing anything with the accessibility page? I think mine may have started with changing one item but now it is all ok. I did undo and change one item in there again. Not sure what happened.
BTW, I find it hard to use the ipad online keyboard using my index finger. I seem to always hit a right tab like when I mean to type "to" it goes to y as in "yo". Never with real keyboard.
