I'm using the app for learning German. First of all, thanks for the great work!
For the last week, I have repeated the same same set of words (~100). No matter do I use web or Android app, each day I see the same words to repeat. The issue seemed to start after a period durin which I had a very weak mobile internet connection. I no more have the internet connection problem but the problem persists. Seem to be a kind of sync problem.
Can you help me, please?
