Honestly this needs zero stars! Constant "errors" at the end of the relentless ad breaks, meaning you then have to re-try, taking you straight back to another 4 minutes of ads before the programme eventually starts, then takes 5 minutes buffering... Why is this app SO BAD???? Channel 4, up your game and sort this out. It's absolutely impossible to enjoy shows using this service, which is a shame because the content is good. This app is absolutely not good enough.
