The summary isn't showing all the reviews I did

Basically what the title says. One example: I just reviewed 世の中 and got it wrong (went back to Apprentice). After that, I was shown this summary:

As you can see, there’s no 世の中 there. I also did the review for the kanji 後 (got it right), as you can see in the items that got guru’d (red mark). This is definitely happening with other items that I get wrong. Not sure if it happens on the ones I get right.

This has been happening for like 1+ week, but I thought it was a problem on the Android app since I’ve always done my stuff through there. However, this also seems to be happening on the website.

Hope any of you guys or staff member(s) can clarify me about this. Thanks!

Sometimes the last item doesn’t appear at first, refresh and it should.

Now it only appeared the reviews that I did in this last round. Is that how it is supposed to work? :stuck_out_tongue:

Wanikani pls.

No, it’s not supposed to do that XD

Well, time to send an email to the WK team, since they seem to prefer to receive stuff through there :stuck_out_tongue:

Thanks for the help ;D

So, there is a known bug about the review dashboard updating being delayed. This is a side-effect of the desired implementation which I believe is being improved upon (read that somewhere last week).

Regarding the resetting of the dashboard, I believe this is on a schedule of sorts, but am not sure what it is. So, if someone knows what it is, please share so we can validate the bug you may be experiencing.

For quite some while I’ve had a similar problem where there’s always one item missing. Like, I just did 8 reviews, but the summary page only shows 7. It still counted all 8 items though.

Sometimes I also have review the last item twice before it puts me to the summary page, no idea why but I always thought it could be because of an addon.

Hey guys, faceless Crabigator minion here. For anyone interested, I wanted to let you know that this is a caching issue with how the summary page is generated. One of our devs is working on a fix, but it’ll probably be a bit before it goes live.


Just did the review for 大文字 where I had to insert the correct meaning twice and the reading three times, all in a space of a minute. Not sure if that helps :slight_smile:

Still seeing this. It’s not the end of the world, but it is a little irritating. :slight_smile:

We’re still working on it. We want to make sure the review summary page is all snappy and happy, but it’s tied into how we record everyone’s reviews, and we also want to keep that super consistent and reliable. So, yeah, we’re taking the time to do it right.

We’ll let you know when there’s, well, nothing to see anymore. :wink:


I have been experiencing this too, lately.

I’ve also been seeing slowness the last few days. Would it be possible to mitigate the problem with more servers while you’re working on a permanent solution?

It’s not a server volume issue, sadly. I’d love to throw some more metal at the problem, but we’re already doing that. :wink:

We scale the hardware involved depending on load, and have the review processing isolated in that scaling logic to make sure it gets priority. There’s a slight delay (like, 60 seconds) between increased load and increased resources, but that’s about it.

Reviews take a little while (usually less than two seconds, sometimes a little longer if there’s heavy traffic) to process. It’s almost always longer than it takes to move from the reviews screen to the summary screen, which is why a refresh nearly always gets you that last review.

TL;DR: Nope. But we’re working on it.


The dreaded “missing last review subject on the summary page” bug should be no longer a part of our kanji learning lives! Rejoice!


Cool, thanks! Incidentally, is this fix specific to the review overview or does this also fix the “it takes up to a minute for lessons to unlock” thing that I presume has the same cause?

The subject progress updates is now handled synchronously, which is the reason for the “instant” feedback on the summary page. Unlocking new subjects is still done asynchronous by background workers, although the operating task should be a lot quicker now since the logic is smarter; it will only check for new subjects to unlock when specific conditions are met. This should mean the background queues aren’t as frequently backed up and thus jobs get processed much quicker. We are already seeing the results of this. Haven’t seen any scaling events since deploying the changes five hours ago :slight_smile:
