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!
It's still not even showing in Studio Beta's known issues section either. Just says "video upload date may not be visible". I guess that's why we're forced to follow their Twitter, it's the only way to know what's going on.
