Channel 4 has great programmes but simply the worst streaming service of all the UK TV channels. It's not intuitive or user friendly at all. I watch it through their Playstation 4 app and it is basically unusable. On All 4 it frequently doesn't even allow you to fast forward a programme and it frequently freezes, so you have to re-watch large portions of programmes. In all honesty it's like the last 20 years hasn't happened to the high-ups of Channel 4, clearly the directors are in their 70's and still find freeview to be a new concept (they are probably unaware that they offer All 4 as a service)
