After updating the consolidated app on my Android, the splash screen comes up for a few seconds, then the app closes without error message... But doesn't stop running entirely, it shows up as a running app window when I pull up from the running apps. Clicking on it makes it close again the same before.

Attempting to open it again using the icon while it is stuck in the bàckground results in an error message that the app is running.

Killing the App and restarting it, or restarting the phone brings up splash screen and closes app as in first paragraph.

I want to try uninstall and reinstall, but don't want to redownload all the books.
