Keep getting logged out

This is something that just started in the last couple of days: Every time I finish the vocab review at the end of a page/screen, I get automatically logged out upon finished the last vocab word. Before it can go to the next screen, everything freezes. I have to click somewhere else on the screen, and it takes me back to the log in page. Then I have to go back to the article I was working on. This is happening at the end of every single vocab review – when I finished every single screen.

Sorry about that! We are familiar with this issue and our team is looking into it. We hope to have it fixed soon. Thanks for your patience.
