I have a questions about using LingQ on Android

When I want to review words, I open the RSR page on android LingQ. If there are 20 words to review, no matter how many times I review, the remaining words are still 20. I have updated the newest version, but still has the problem. Is it a bug? I have to use website review words. Why? Does anybody have the same problem? If anyone know how to solve it, please tell me. Thanks very much.

Yes, that’s a bug at the moment, sorry. We will have it fixed.
