Really sorry you're running into this issue with the Sorting Activity lesson. We've got this logged as a software bug, and our team is looking into next steps.

In the meantime, can I confirm what iOS version you're running and what browser(s) you experience this issue on?

We appreciate you bringing this to our attention. I'll update our bug report to include this discussion thread. That way, you'll be notified once we have an update!
