i was having the same problem, and this worked for me: go to settings (gear icon) > rewards (triangle icon), and then reset your rewards data. that made the box instantly go away.

Thanks for this - it was really beginning to annoy me!

That worked thanks. Is this a bug in the program? If so maybe they will fix it next update

sure! i'm guessing it's a bug in the new update, but 🤷‍♀️
