no option to report correct solution (again)
In the course Norwegian from English an image was presented as 'write "a dot" in Norwegian'. My answer "en flekk" was not accepted.
But the real problem is, that there is absolutely no possibility to correctly report the error, because the report button only had one option ("the pictures don't match the text") and a discussion button was missing throughout.
This happens very often (see https://forum.duolingo.com/comment/28350397) and is very annoying.
