Hi Dani,
Initially I tried it on my tablet via Horizon or UPC TV app and SyFy channel wasn’t there. I tried via browser on my PC and it was the same, SyFy channel not in the list of streaming channels. I can see schedule ’though but nothing more than that.
I just tried UPC TV app on my phone and it’s the same situation, SyFy doesn’t play (e.g. all 3 TNT channels in same subscription I can play).
It could be something weird with my account, more than 3 months ago I switched on Premium+ channels but they were not in my original subscription.
BR,
Alex
