Sign out of all devices

@detuch254 When you keep repeating false advice that doesn't work, none of us appreciate it. You're wasting people's time and adding to the frustration advising things to try that you already know won't work. Wouldn't it be better to honestly state that there is currently no solution to this problem than to give people false busy work? And I see you're just as rude as your counterpart. 

@bcbsncjlj That is not true. From the AT&T website, here are the (now defunct) instructions how to get there on the app: View and manage your DIRECTV STREAM devices

Manage your DIRECTV STREAM devices. Also find out how to return your device and learn more about auto-sign in.

DETAILED STEPS

Manage DIRECTV STREAM devices

Sign in and go to your Account Overview page.

In the My streaming devices area, select Manage. From here, you can:

View a list of your devices. 

Disable auto sign-in by turning the selector Off next to “Auto sign-in.” If you have more than one DIRECTV STREAM device, this can be taken for each applicable device.

View installment plan details, if applicable.

Add more streaming devices (up to 6).

Only for DirecTV Stream devices purchased from DirecTV. That is because the DirecTV Stream devices are registered to the user. Roku, Fire Sticks and even DirecTV Stream devices purchased from other places are not registered to the user. That is why all the subscribers purchasing devices from other sites, like eBay, are having major issues.

You need to understand that most all the info and FAQ's are based on the DirecTV Stream box.

While I can understand issues with them being able to report what devices are in use - in most cases there really isn't a mechanism for them to identify specific devices or  report where a device physically is or who is using it - they have less excuse for not providing a mechanism to sign out all devices.  They should be able to (safely) do this through the account management pages - anyone who can log into those can pretty much do anything to the account anyway.  Clearly the system has the capability to flush an account and bounce all devices, so bouncing devices without flushing the account certainly should be possible (and apparently was at some point in the past).  Note that I don't think the instructions referenced about "auto sign-in" would provide any help in forcing a device to log out - they would just allow you to force it to explicitly log in the next time it happened to be logged out.

I have the same issue. Unfortunately the  only way to correct an issue such as this is to cancel your subscription and then redo it.

Except I can't because I'm grandfathered in on a plan and pricing that no longer exists.

Then I guess you will have to live it. Sorry for your issue. At some point, it will cease to exist.

@bmstanifer not sure if your issue ever got resolved, but I was in your same shoes and grandfathered so canceling was out of the option… or so I thought. It just so happened they “accidentally” canceled me on their end one day and then refused to give me my grandfathered plan back and boy was that an enlightening experience. I was able to get almost all the channels I needed elsewhere. It may not be what you wanted to hear (and completely ignore me if you’re on a tier with a channel that nobody else has) but the other services have come a long way and the grandfathered plans aren’t as great as they seem anymore, especially given what we’re paying for them.

Yeah it isn't an issue for me anymore either. Almost all the channels I want to see are available to me for free. I don't really need cable so I just let it go. I am bill free and happier now. 

@bmstanifer even better. I just can’t support a company that will leave you hanging just like that. The closing my account after me paying so much for so long just to stay grandfathered was the final straw.

They sent me a notice that they were raising my "grandfathered" price to be the same as everyone else so I didn't see a reason to hang on. So much for 25 years of loyalty. 

The service has not been available for 25 years! So your loyalty is based on somewhere else.

Happily canceled my DirectTv/ATT plans so I no longer deal with this (Edited per community guidelines).  YouTube TV is working great for me. 

Enjoy your new adventure.
