Wanting app to force log off and re-login

I am very frustrated with the customer service side of technical support. I have called and talked to 4 different people and been told a different solution each time. I recently changed my password for my ATT login because I was logged into a neighbors smart TV to use my account and watch tv. We are no longer friends and I have recently found out they are still logged into my account and use it to watch my service on their smart TV. I wanted them to be forced to log off and not be able to log back in so I changed my password two days ago through ATT. Directv kicks me back to the ATT site to manage my account since it was originally ATT TV and was provided by ATT so I am unable to find any way to change a password through directv directly. None of my devices are asking me to log back in. If I manually log off and log back into Directv Stream it accepts my new password but if I just exit the app on a device that is already logged in and re-open it, it never asks for my new login. Each agent has told me completely different things. I was originally told I needed to wait 24 hours and it would force new logins on signed in sessions. Didn’t happen. Then I was told it will never force anyone to log back in if they do not manually log out which is NOT protecting the customers security and account and absolutely ridiculous. Then I was told it could take up to 5 days to force all devices to re-login. I asked to speak to a manager in technical support 4 times and was never offered the chance to speak to anyone else. I called back again and spoke to someone else who said she also wouldn’t transfer me to management because it’s not a manager issue and she told me I should change my user ID because it won’t force anyone to log back in with just a new password.- I changed my user ID as advised just a little bit ago and it’s not forcing a log off either. Possibly because I just did it. All in all very frustrated -.- This can happen to anyone just traveling and forgetting to log off a device at a BNB or vacation home. Why is there not a more standardized way to handle this? Can anyone in advanced technical support please chime in? Thanks
