We are aware of an issue with some Android devices being stuck on the loading screen. If you experience this, some have had success with uninstalling the app, rebooting their device, and then reinstalling the app from the Play Store.
We do apologize for any inconvenience. Our Dev team has been working on this issue and has an update in testing. Once this update is confirmed, we will release an update to the Google Play Store... We appreciate your patience with this issue!
