When attempting to use the Content Translation feature to translate https://de.wikipedia.org/wiki/Harald_Braun_(Diplomat) from German to English, I am blocked by a message saying that someone else by the name of ParovT has already started a translation, and that I should coordinate with them. However, this username apparently does not exist, as when I click on the name, it cannot be found on Wikipedia. So, I am neither able to work on the translation myself, nor collaborate with this nonexistent account on it. This is occurring on Chrome with a Windows desktop.
