I haven't had chance to watch any F1 tonight (watched a little this afternoon).
Just wondering if the Sky Sports F1 channel is still out of action ?
If so, any error message or error code on screen ?
Just tried Sky Sports F1 myself on my Roku and no problems for me watching this channel.
I am guessing you have done the basic stuff like a temporary power down on your Roku and Router.
A couple of forum members have reported over the years that all their Sky Sports Channels was running fine apart from one (usually it was Main Event or Premier League)
I can't remember if they changed the wifi channel on their Router or switched to 2.4ghz or 5ghz or vice versa on their dual band Router and then reconnected to the new wifi network again on their Roku.
