DuckDuckGo app out-of-date
The version available on F-Droid is 3.0.14: http://fdroid.org/packages/com.duckduckgo.mobile.android/
but the latest version released is 3.0.17: https://github.com/duckduckgo/android-search-and-stories/releases
I work for DuckDuckGo and am happy to help if there's anything needed from our side.
Thanks in advance.
