Error in "Ce chapeau, c'est le sien." (fill in missing word) prevent me from completing the lesson
Hi, In the Fill in the Missing Word problem with the sentence "Ce chapeau, c'est __ sien." the correct choice should be "le sien", but it is not accepted, likely because "sien" is already (incorrectly) there to start with.
There is no way to satisfy the system with the fill in the blank (e.g. typing in the incorrect answer intentionally), so I cannot complete the lesson, and since I am doing "Strengthening" lessons, I keep being put back to the same lesson to begin again, which keeps eventually stopping me at this problem. I cannot report the problem with any details because the report mechanism is limited to two check boxes in this case with no comment field available. How can I escalate this issue so I can get back to my studies?
