I did all of above — was a DIRECTV satellite customer, switched to DTV Stream, set up a Stream account with a different email address (given my DIRECTV.com and ATT accounts were/are linked). After multiple subscriptions, testing, and cancellations and restarts, finally was about to access the Stream app on iPhone and 1 fire stick TV, but have not been able to access Stream on another fire stick TV or a ROKU TV. Each throws a care code 902 upon login attempt with new Stream credentials. So doesn’t appear to be specific to Roku or Fire; apparently an ongoing conflict with deactivated Satellite. No one at DIRECTV Stream has been able to resolve. About to execute final cancellation — after days of vacation time wasted. DirecTV should be harshly reviewed for what they’re putting long time customers through, while still charging a bundle for Stream. Clearly no regression testing. Had been with DirectV since ‘83 — loyalty now well beyond exhausted.
