Is anyone having issues more now with using the Dispney plus app on Android TV. I know have the constant code 83 issue on chromecasts and I've done everything they say to do with no luck. Also now having issues on the Nvidia Shield. These devices are also in different zip codes and ISPs
When I was encountering error code 83, it turned out that the adblock running on my router is what kept causing it.
Turning off all forms of adblock from the router and my devices solved the issue for me.
