I got a new smart TV with Android 9, build PT02.200520.001, Kernel-Version 4.9.118+
First thing I sideloaded Firefox and Blokada to get rid of some ads.
When I tried running the (system app) Prime Video (version 5.4.2-armv7a com.amazonvideo.livingroom) I got a connection error. Nothing I did soved it, but when I disabled Blokada, it worked.
I couldn’'t find any entry in the log of hosts blocked, but for some odd reason, both apps can’t be active at the same time. Now I added the app to exceptions, to be able to benefit from Blokada and still have my Prime Video.
I am using Blokada 4.10.0
