GAA+ on YouTube
I think YouTube removed the rights restrictions recently, and there's a whole load of sports streams there now, including GAA+. I've seen a lot of comments saying they can't access GAA+, but there's always multiple streams on YouTube now, which is how I watched Waterford vs Cork last weekend. Quality can be a but iffy, but it's better than nothing.
Just to be clear, I know people hate it as older people can't access it, which is terrible on the GAA's part, but most people will be able to access it now.
If this fails, there's always a dodgy site (daddylive) that has GAA+ on it too.
