I'm using my Bravia KD-49XE8077 with my Amazon Echo Plus and Sony's Android TV Alexa skill in the UK.

This was working fine up to before Christmas.

However, now, whenever I ask Alexa to do something (turn the TV on/off, change the volume etc), the TV responds, but five seconds later Alexa says "Sorry, TV is not responding".

As I said, the TV is in fact responding, so obviously there's some issue with this being reported back via the Alexa skill, and previously this was working (i.e. Alexa would just go bing to confirm, as it still does when I use it to turn my lights on/off).

I've tried delinking my Amazon account from my TV, disabling the skill through the Alexa app, obviouly rebooting everything multiple times, but nothing I've tried seems to fix this problem. And as I said, it was all working properly not that long ago; I'm not sure if there was an update for one of the things involved that has caused the problem.

Has anyone had a similar experience and found a way to fix this?

Thanks.
