1. Youtube Subscribe button is given
2. Another button named "Next" and it is disabled by default.
Now when the user clicks on youtube subscribe button and subscribes to the channel, the "Next" button show be enabled.
and if the user is already subscdibed to the youtube channel then "Next" button should be enabled already.. I hope you understood what I want..
I want to lock a content and unlock only if the user subscribes to the channel.. thanks
