If you’re seeing “No Subscribers” or “0 Subscribers” on a channel when you know that’s not the case, we’re experiencing an issue with the way sub counts are displayed – it’s happening inconsistently across a number of channels. We’ll let you know as soon as it’s fixed!
This is why you shouldn't change stuff when it isn't broken, especially something as trivial as a subscriber number. At least change it so REAL numbers are shown in APIs so that way sites like SocialBlade can provide real data, not rounded sig dig numbers.
