Thank you for the traslation. In order to complete the translation please create a folder pl in the fastlane/metadata/android folder and in the folder add two files full_description.txt and short_description.txt In these two files translate the contents of the two corresponding files from the folder fastlane/metadata/android/en-US folder.

@xxxcucus I seem to be missing the strings you quoted.

[xxxcucus]

You have taken the strings.xml from the planes/java folder. The app is now built from the planes/kotlin folder now as it is a Kotlin app. Sorry for noticing so late. Please add a commit for this folder (planes/kotlin/PlanesAndroid...) as well
