I bought a new Fire TV stick from a mainstream dealer - mainly to watch Grand Tour on my television, because I cannot cast it from my phone. So I note again that I am able to watch Grand Tour on my phone and also on my laptop.
The error 5505 comes up on the Fire TV screen when I try to play Grand Tour. The device even synchronise with my account on my phone - I can see the last episode I watched and resume where I stopped.
I have tried various tips, tricks and advice and still no success - account regions settings, clear device memory/cache, deregister account, reset device.
