Bug: Lingots debited when clicking to buy a certificate, but cancelling on the confirmation popup
I just ran across a glitch on the Duolingo website. I was on the Lingots store webpage, I clicked on the "Certificate" button, but when the pop-up opened, stating it would takes ~20min and asking me if I wanted to proceed, I clicked on "no" and then cancelled.
However, my lingots credit was debited all the same.
25 lingots may be quite an amount for some users, so I thought I had to report that bug ;-)
The alert asking if you wanted to proceed or not was for taking the test at the moment.. Essentially you've purchased a test, but are free to take it at any time. When you're able to take it, you can go to the store and click it to begin the test - you won't be charged again.
