Until recently new shows or seasons of shows on NOW would be automatically be added to the ‘watch now’ list on Apple TV but this appears to have broken and they no longer appear which means we have to go and search for them in the app instead. Is this a known issue?
I have had a very similar problem arise within the last week. When I watch a programme in NOW it does not update the information in MYTV and the watchlist. I'm using a different platform to the OP. I have NOW as part of BT TV on a SONY Bravia.
