I know this site isn't optimized for mobile use on a smart phone, but I've had to deal with two annoying issues when trying to post:

I'm on iPhone 6S. Latest iOS.

1. When trying to write, as I type, the screen doesn't move with the cursor, so I end up writing off screen. When I get to the second line of my post, the screen starts to move with the cursor.

2. At random, while typing, the keyboard disappears. I have to click into the text box again to make it pop up again.
