Service Web: Error "109. We are sorry. Your request cannot be completed at this time"

I experienced the issue yesterday while using Microsoft Edge. I don't have this issue using Chrome, Firefox or IE. The error occurred for me after logging in and clicking a user's name to view their account. I didn't try the Billing tab before resolving. It was resolved by deleting the cache and reopening the browser.  

I've seen this over 30 times over the last week while trying to do out initial setup
