Cant adjust the font size on iPad Pro and the ads keep popping up on paid version.

On ipad iOS 10, the words have become super tiny even though I set the font size to 200% and also set the font size to the maximum on the iPad. This is really disturbing and this problem has been existing for over a month. To be worse, the pop-up ads keep showing on the paid version. I dont even use this app on iPad now.
