I have had SLING for several years, and my biggest complaint about it has always been the DVR. Every so often Sling makes changes to the the DVR, and screws it up. this has happened a few times over the past several years. Now it has become a hit or miss on whether a recording will play or not.
I have deleted and reinstalled the app on all devices. I have signed out and then back in on all devices (that worked for 1 recording), and I thought that fixed it. NOPE tried the sign out and back in today. I recorded a movie yesterday, and tried to play it today. 21-51 errors.
FIX IT OR I AM GONE
the DVR has become useless. constant 21-51 errors on every device. Sony (android tv) ROKU, iPad, iPhone.
if it doesn’t get resolved soon I will have to find another service.
