Unfortunately not. It would simply take too much time and effort to convert it for every language. We do try to work with support using Google Translate when possible and it seems to work okay.
When we get a response from YouTube that a send was not successful, we look at the error message sent to see why it was not successful. If your YouTube account is not setup as English we can’t interpret the error so we code it as "Unknown". Once we get 5 unknown errors we stop sending.
Your messages can be sent in another language but your account needs to be in English for our software to interpret the error messages.
At the bottom of the YouTube page is the information below – you can change it there.
