The Kindle app was not running on my Likebook Mars this morning. Since I had an epub to read on Libby, I used that instead. This evening, the Kindle app still wasn't working. I went to Google Play to update my apps. It updated other apps but not the Kindle app, the Nook app, or Libera. It ended up uninstalling the Nook app and reporting that it could not install it. It would just stall and fail to update the other two. It would also not let me run them. I rebooted and cleared the Google Play cache, but it didn't help. I uninstalled the Kindle app, but I still could not reinstall the Kindle app. The Kindle Lite app works, but I prefer the regular Kindle app. Is anyone having similar problems? Or does anyone know what else I can do?
