Nice update but introduces issues

I really like the new interface, but performance has degraded considerably and eventually crashes on my iPad mini 2. It has also introduced some new issues, Ive noticed that on some exercises the last answer is not pronounced before moving to the next exercise. There are sometimes issues with progress being saved and forcing me to redo exercises. And last, I used to be able to pause a lesson and take a look at the correct answers, now when you pause, the lesson disappears.
