I was wondering if anyone else was having a problem practicing old words with the free subscription. I can only practice about 20 old words, then I get my 50 new words for the day, then it tells me that the algorithm says I have no new words to practice, even though my country on the left says I have about 1800. If I click the button to get a random card set, it just tells me the same message again. I also cannot email the company or file a bug report without the unlimited subscription, so I guess I am a bit stuck here. Has anyone found a fix?
Happy language learning, all!
