Hardware / Software

OS X 10.13.5, Chrome v67.0.3396.87
iPhone 6s, iOS 11.4, lichess v6.0.0

Summary

I completed a few dozen puzzles using the web app on my Mac. Later in the day, I attempted to resume my studies on the iphone app. I discovered that while my puzzle rating history was in sync, the state of my puzzle progress was not; the mobile app was providing me with puzzles that I had already completed. Completing these puzzles again does not affect my rating.

Expectation

As a lichess user, I should be able to complete puzzles in the web app on my laptop, and later resume my puzzle progress in the iPhone app. Lichess should "bookmark" my current puzzle, and sync that state across devices.

Repro Steps

1

11:44am -- Log into account on lichess.org. Visit profile. Observe puzzle rating (1560) and number of games played (69) in sidebar. (_Disregard discrepancies in the Activity feed section; out of scope for this bug._)

2

11:44am -- Navigate to Learn -> Puzzles. Observe rating in sidebar (1560). Observe +/- history (green/red blocks) below puzzle. Observe current puzzle ID (61210).

3

11:45am -- Open lichess app on iPhone. Navigate to Training. Observe that puzzle rating (1560) and +/- history are in sync with web app. Observe that puzzle ID (61150) is lower (older) than the latest puzzle presented in web app (from step 2).

4

11:46am -- Re-solve puzzle 61150 on iPhone.

5

11:46am -- Open rating graph. Observe that neither rating nor +/- history have changed. The next puzzle offered (61153) is also an "old" (previously solved) puzzle; in other words, still behind 61210 from step 2.

6

11:50am -- Return to web app and refresh the page. Observe that rating and rating history have not changed. No progress has registered, since the only puzzles completed on the iPhone app were "old".
