Grammarbot on German for English Speakers

I would like to ask you all is it possible that there are only 3 grammarbot lessons for german language? I have finish first 2 classes and I am on the good way to finish also German3 but whenever I select grammarbot, it keeps looping just simple questions, kein and nicht. nothing new

Can someone told me what am I doing wrong?


Here it is 2020 and this still hasn’t been fixed. It’s very annoying, more so because so many people have reported this bug. Does anyone at Memrise even read these?
