Why can't I activate my Premium license on OS older than Android 6.0?


Google releases new versions of android with a year cycle. In process of which developers write some more useful API, methods, classes which are powerful than existing one. So app developers need to use newly written API’s and depricate old methods.

Android 5 and lower are officially no longer supported by Google and that affects our dictionaries as well. So the way around this is to update to Android 6 or higher.
