Hello @bruzote, I am sorry to hear that. Unfortunately, there is no way how our application can work on Android 6 devices.
As of September 2019, Google is no longer supporting Android 6.0.
Android 6 is 6 years old and new technologies that are used aren't compatible with it and the application would be buggy – that is why we can't release Windy for Android 6.
We don't make older versions of our application available because it contains bugs that are already solved but also features and elements we wanted to get rid of.
