@TeamYouTube I'm trying to transfer my subscriptions from one account to another so I can stop using the main one but you've barred me from subscribing for hours. It doesn't even tell you who subscribes to you, this doesn't make sense.
If you're referring to subscribing the same channels, you can simply hit the 'Subscribe' button – refresh the page after. Also, do some troubleshooting, like clearing your cache and cookies and restart your device. Updating the app would also help. Let us know if that works!
