I've used the following stream services BBC iPlayer, Netflix, Crunchyroll, Funimation, Disney+, and I can safely say the advert that plays on Channel4s streaming service about it being the best streaming service in the UK is a blatant lie. There are usually 4 sets of ads, ranging from a minute to 4 minutes each. Some of the ads I found difficult to watch, but mostly it was so interrupting, and often the subtitles would reset, not work or be inaccurate. The only good thing or redeemable was the content, however, at some point if they don't step up, I would just not bother with it any more. Too many streaming services will give way to people illegally downloading TV series and shows again
