Hi everyone! I want to confirm that we did launch a feature to catch typos in visible kana, but we realized quickly that there were bugs in our algorithm so we disabled it as soon as we realized that. I’m sorry to everyone whose workflows were affected in the meantime. The plan for this feature is to catch genuine typos but still allow people to fail a review deliberately. So we’ll go back to the drawing board and post an update once we’ve figured out how to get there without the unintended consequences. An “I don’t know” feature is also something we have on our radar!
Sorry again for the inconvenience, and thank you for the feedback, it’s always appreciated.
