At the moment, the last present version available through the Google Playstore, version 7.4.53 has problems when run under Android 6 and above. A simple fix is to use a previous version, 7.4.43 and not let it update to the newer version. To be able to install this version, you will - temporarily - have to allow installations from unknown sources in your Security preferences in Android.
