I had the same problem with my Nexus 9 (With a custom rom) and now with my new Chromebook (it is using Chrome OS but allow to install Android Apps)
After do lot of tests, I could see the problem was that “Android System WebView” wasn’t installed/updated, and because of that the app keeps stuck before the login screen.
To fix it, you only need to install/update “Android System WebView” from Google Play Store and it should fix your problem.
