I was invited to a shared box my Andrea Maciel and again by Ben Kurzius “Lee County HFA - Hawk's Landing Bond App” when I try and access the folder an error message states: “Oops! We can't seem to find the page you're looking for.” 

Additionally, If I’m just in my regular box account and go to notifications I see the request from Andrea Maciel, but when I click accept  I receive a pink error message stating “Oops! There was an error. Please try again later.”
