That's really strange. I just checked, and there's absolutely no issues for me. Maybe did you try it on other devices? Maybe there's something with permissions on your current one?
Wait, are you trying to save the n the save page with "A" instead of a number from "1-9"? Because I am having a an issue similar to what you have described there. That will still need to be fixed, of course. But for now, maybe try saving on a different page?
