Repeated tactics when switching from browser to Android app

After solving tactics on the browser, if I switch to the Android app, it'll show me many repeated puzzles. Is this a bug or am I missing something?

Furthermore, solving (or failing) doesn't seem to affect my tactics rating on the app. Also, the rating on the app is different from the website. It's all a bit confusing.

I’ve noticed this same problem myself. They seem to be independent of each other.

FWIW, I've found this bug report: github.com/veloce/lichobile/issues/831
