I am having precisely the same problem. I just don't understand the steps to fix it. I have tried uninstalling it multiple times, but it only works once, and then when I go to access it again, it crashes again, and I have to un-install it again. Can somebody please explain how to delete the cache and app date? (I have a Samsung Android phone.) I read somewhere else that I need to install an older version. Should I try doing that? If so, how do I do that? Thanks in advance!
