I’m curious… how does Channels on iPad manage its storage usage? I was surprised to find it consuming more than 4GB on my iPad, which doesn’t have a ton of free space. Maybe this is expected but I thought I would check. I submitted diagnostics before deleting and reinstalling the app to free up the space.
Were you using remote streaming on this device? That's one place we cache the video to improve playback.
Yes I think I’ve used remote streaming on it at least once on the past. Not often.
Maybe there could be a "Flush Cache" command under Settings > Support or something, so we don't have to delete and reinstall the app just to free up space.
