German 2 482/486 words, but no more words to learn

As the title reads. I finished this course, and it says so on the app, but I still get the prompt to learn new words, especially when I’m online, and then get this message:

“Could not load the session. Sorry. Please see this support page for more details”

Are there actually four words that I cannot access for some reason? Does it have to do with the grammar?

This problem has been fixed for most courses from what I remember.

I’ll tag @MemriseSupport and @JBorrego, they could check and might be able to shed some light on this.

I’m having a similar problem on my German 1 course. I have 9 words to go, but I have already learned all of the grammar topics on the app. Regardless, every time I try to “learn new words” it brings up an error message.
