Brazilian Portuguese 3+ Error

“Sorry, there was an error loading the session!”

Does anyone else get this error when trying to open a Brazilian Portuguese course past level 2? I would have figured that it was a space issue since there are 673 words so I freed up over a gig of space but nothing. I also removed all the other courses I had open except level 1 and 2 portuguese, that didn’t help either. Level 3 is open, but there are no lessons visible. I can tap “learn new words” but the error shows up again.
I tried doing a lesson on the website and it works but nothing shows up on the app, I’d prefer to continue on the app if I can help it, though

Thank you
