There are two types of issues you can report when it comes to language courses. You can report specific sentences, or you can provide feedback about the language course in general.
When you have feedback about errors in specific sentences and translations, please follow the steps aligned here. This feedback goes directly to the course maintainers, and they collect these reports to fix mistakes and add possible translations to the phrase.
If you have general feedback about a course or language (such as the voice used, grammar questions, or just praise for the team), please communicate directly with the Incubator team for that course. You can contact them via their course specific forum:
