I’ve been in level four for weeks, religiously doing review every day, with a good accuracy level of around 80%. Says I’m on level four but only shows items from level 2. No new items are shown and when I try to access level-up page on wkstats website seems stuck loading page.
Could it be a bug in the app? Issue with my account? What should I do?
Have you paid for a subscription? Only the first three levels are free.
Seeing as your level flair is greyed out and marked as “free” you don’t have an ongoing subscription and therefore you will not get any more lessons until you pay.
I am an idiot. I totally forgot about that, you were spot on. Just paid for the lifetime subscription 
Thank you very much!
logging out and back in will update your level flair.
