Current version is buggy

I love this app, but since the recent update, there are several bugs that are show stoppers:

1. Rather than stay logged in, you now have to enter your credentials every time you open the app. That means my child cant use the app unless I login for her.
2. A book in Level 3, Lesson 22 will not open. It freezes the entire program and the only way to get out of it is to close the app. Unfortunately you cant advance to the next lesson until all activities in the previous lesson are complete. So my daughter is unable to advance through the app any farther.

If ABC Mouse doesnt fix these bugs, the app becomes basically useless, which is unfortunate since my daughter loves the content and is eager to get back at it.
