ATT / DIRECTV GALAXY VIEW TABLET - Shut out of Directv APP

Guys,

There are plenty of people who own the GALAXY VIEW tablet. This is a tablet that was sold and marketed to Directv customers
with exclusive access to DIRECTV APP.  The app is BUILT INTO the operating system. 

(Again DIRECTV/ATT Tablet - $800.00) 
Model SM-T677A  - Android 5.0

Directv app requires update to work. 
Play Store update - 'NOT COMPATIBLE WITH YOUR DEVICE,'

Our Directv Tablets are not working. There is NO option to uninstall as it is built into the OS.

PLEASE FIX THIS SO WE CAN CONTINUE TO USE OUT GALAXY VIEW DIRECTV TABLET. 
Completely not fair to all who purchased this tablet through DIRECTV/ATT

Again - The only option we have is to update through Google Play Store which then shows INCOMPATIBLE.

PLEASE do not respond with useless instructions.  This is an ATT/DIRECTV tablet and there should be NO reason on to why we would be cut off from using this. 

This can only be fixed by the app developers. If they are not planning on fixing this please reply and let us know. 

Otherwise Directv/ATT will have to honor some type of refund or compensation for selling us a DIRECTV tablet that no longer allows DIRECTV
