Stopped Updating Content

I love the app but it stopped updating the videos - It got stuck somewhere in the middle of January. I removed it and re-installed. I got the new content, but they charged me again, another $4.99! Also I dont like that I cannot change the size of fonts in the text. The font is too small for me.
