+Those strings still appear as untranslated to crowdin translators.

+If you want to use a string in your code that can't be translated, please use:
+
+* constants.xml if the string must be a constant, such as the name of someone or a URL
+* hard coded string literals if the string should not be translated because it belongs to a feature in progress.

     Adding or removing new line at the start/end of the string cause crowdin to require a new translation. Let's check if a comment before lead to a translation need!
