When on mobile (and sometimes in browser), sometimes you click on a stream, watch the ad and then if you have to minimize the app for whatever reason, or swap between streams, there should be a "cooldown" on the ads for the channel. If I JUST watched the 30 second ad on a channel and accidentally hit the back button or closed the app, I have to re-watch that 30 second ad every time I join the stream again. It would be great to have a cool down on the ad refresh rate, so that it can be easier to watch multiple streams at once, or even to find new streamers to watch.
