Custom Reports (Create a Report) Error

For the past week, I have been unable to access custom reports. Everytime I attempt to access I cent an error "Sorry, something went wrong loading the requested data. Try refreshing the page, or try again later."

I thought at first it was an error accessing from my phone, but when I tried today, Sunday 12/06/2020, it is continuing. Is anyone else getting this challenge?

Guessing this is using LCR in a web browser. If so, clearing the browser cache and deleting cookies _might_ make the problematic symptoms go away.
