Too long to load

Nothing has changed with the new update. In fact, with every "update" it takes longer and longer to load.

It takes much longer to load with new update. I sometimes walk for 2-3 blocks before it will load. It also closes when I open another app (e.g. Answer/read a text when walking), and also closes at random.
