For folks who are interested in the details:

Symptom

• You sign in successfully, but see the error message "You are logged in but we are unable to access your account details, try again". 

Differential Diagnosis

• This is happening in Dec 2020 (If you're googling this a few months from when it was posted, you are not encountering the same issue).
• Other account issues can cause similar symptoms. 
• Please confirm your issue is not one listed in our other stickied post.
• Not every issue you encounter can be diagnosed without account research.
• This is a generic error message, and if something else is wrong with your account it may be another reason that is causing this error message to appear (we've actually had a few of those pop up too).

Background

• We have an identity database with settings and configurations for your identity with the following relevant fields:
  • cstAccountStatus
    • If you have service and the billing system agrees, it's set to "A" for "Active" and shows in My Account you have service with us.
  • cstDetailedAccountStatus
    • For everyone affected has been set to "NULL" where everyone else is set to "Active"
    • When switched from "NULL" to "Active" the affected user is fixed.
• Only higher tier escalation teams can make this configuration change. 

Root Cause

• TBD, but here are some initial thoughts...
• My Account looks at the Identity database to determine if you still have access. 
• We believe it's a misconfiguration within My Account that recently changed that affected a small crop of our customer base, where cstDetailedAccountStatus is now being read (it wasn't read before, meaning you didn't experience the issue before, even if you had the "NULL" setting in cstDetailedAccountStatus.

Is this an outage?

No, this issue is affecting .03% of our customer identity base, but highly represented as a support issue, hence the importance and priority in getting it fixed.
