Using Chrome Browser.
I was doing an infinite review of 122 words in my pool using text-input.
At the end of my review, the blue review button for 122 words popped up again. I ignored it, suspecting it to be a bug and went to my dashboard. True enough, I didn’t have another 122 words to review. To see if I could go back to the screen suggesting I continue reviewing 122 more words, I hit ‘back’ on my browser.
It returned me to the final sentence I had finished reviewing… except it allowed me to review it again (I went from 0% to 25% in my initial review and then re-reviewed it to 50% within a couple of seconds). I input the correct answer, bumping my score up again and it sent me to the next sentence in that previous infinite review session. I imagine I could have re-reviewed that session as many times as I wanted to.
I hit the dashboard button again. I tried to hit ‘back’ to see if I could replicate it… but now the infinite session won’t load (which is a great thing).
But I’m worried this can be exploited. The next time I have an infinite review session, I will see if I can intentionally exploit it to mastery (not for points-sake, but to see if the bug is repeatable).
