Can a subaccount access the Uverse App?

I set up a sub account for my daughter.  She uses it to access the U-verse app and/or  authenticate to individual channel apps all the time.

Thanks - I just wish someone could tell me how.  My email is listed as a subaccount.....

I used to be able to access Uverse app for a long time.  A switch got flipped somewhere.  I appreciate your response.   

A lot of users seem to be having issues with the U-verse apps these days.  You can try changing the password.  Sometimes that helps.

Also, more than one sub account can be created.  If the primary att.net email account is not working correctly, and by that I mean it doesn’t work signing in to other network websites or even the att.com website, that needs to be resolved, perhaps by resetting the password.
