Off topic, why can’t I consistently watch videos from d.tube on my iPad? Sometimes it works sometimes not, sometimes a video I have already watched won’t play but then later it will?

I keep getting broadcast error or content not supported! Anyone else experience this and what should I do too correct it? Do I need to pull out my laptop just for steemit? It’s an old beast but should work alright but I don’t want to reinstall the whole thing(virus) if it is a network thing.
