@abby-flowp not sure why the test is failing here. I can approve the changes but don't know if it'll get reflected on the website. It might be because of this "Settings → Notifications" Maybe you can't have ` across two words

@UnicornGunnerz another good point to add on to this page is how to avoid getting tests failed lol
