How to identify unknown charges on Apple Account

Hello All,

I just received an 83.99 unknown charge. It was from Duolingo after their first full year of free service. I see that there were a lot of posts and no replies on what it actually was, just how to dispute. were closed so I thought I would post the solution in a new reply.

If you click on the transaction on the wallet app and if bought with a Apple Card, if you report an issue on the card and click through, it will show you the transaction history for your account and any family account members and identify what the charge was for.
