"I'm not aware of anything, Mrs. police officer."
Translation:Je ne suis au courant de rien, madame le policier.
They don't come to look at the forum. If you have anything to bring up with them, click on the flag and either just tick an appropriate box or write down the problem under "something else".
If you have a problem with the app you want to tell them about, go to your personal section and click on feedback. Though don't expect an answer.
Those who help us out are volunteer mods and they have no more connections to the makers of the app than we do. HTH
"Mrs Police Officer"??? Really? Duo, who is writing your questions? This would NEVER be said by a native speaker. In my country, you could easily end up on a charge for just speaking to a police officer in this fashion. Please do better quality control on these modules.
