No longer running from today. The system has not changed in recent times. No mobile Internet and wireless rarely. "Amazon Appstore: Unknown error An error occured Please download this app again from the Amazon AppStore.." Although not necessary, the app probably needs an Internet connection. However, this is not documented anywhere or mentioned. Very annoying when you're on the journey and can not access the Internet. degree because, on the journey, you have also time that you want to distribute. The apps from Google Play store, in Gegensatzt, but will continue to function. This fehelermeldung can also get the same, although the smartphone was a few days ago in the domestic WLAN and the app is running. So you can not in advance "voratmen" so that the built-in Amazon DRM nechsten days are calm. The perfidious is that the error message of unknown error speaks obwhol support very wol know why. The support gives the developers of the app, the blame for the behavior of DRM, although obviously the error message from Amazon was installed. I have certainly no desire to me this app, as suggested by support new downloading (which I would have to make for the 2nd time). So I would never have any app on the Amazon Appstore relate that costs something. Good thing it was free
