The delays in the streaming really can't be fixed completely. There's a limit to how fast that data can move, but I agree on the notifications. I can hear my phone going off but I don't check it while play is going on. But, this holds, to a lesser extent even on satellite. I've seen tweets of a goal scored 10-15 seconds before I see it.The biggest issue (for me) watching on a streaming service is it's generally about 30 seconds to a minute behind. So, if you get alerts on your device, you will be spoiled. I don't bet on games, but I would imagine that could be an issue for those who do prop bets? Not sure. As I said, the major issue for me is recording games. I have other ways to watch live if I need to if Fox goes away.
I wish they went back to "Must Carry" rules, but I get the networks need ways to make money so they opt out.
