Affected version

30.11

Device Type

Smart TV/Box

Affected Android

Fire Stick 4K

Steps to reproduce the bug

1. Open SmartTube and go to a channel you are not subscribed to.
2. Press the Subscribe button. The button state changes to "Subscribed" within SmartTube.
3. Go to the official YouTube website (in a browser) and check your subscriptions.
4. Observed Result: The channel is not found in your YouTube subscriptions list.
5. Conversely, channels you are already subscribed to on the YouTube website often show as "Subscribe" (unsubscribed) within SmartTube.

Actual behavior

The subscribe and unsubscribe functionality within SmartTube is not properly synchronizing with the main YouTube website.

When I subscribe or unsubscribe to a channel in SmartTube, that change should be reflected immediately (or after a short sync period) on the official YouTube website, and vice-versa. The subscription state should be consistent across both platforms.

Additional information

1. This issue occurs consistently across multiple channels.
   

2. It affects both new subscriptions and the initial loading of existing subscription states.
