I paid my premium payment for youtube. But in youtube app it is not working

Hello Varun3435,

Thank you for reaching out in Apple Support Communities. We understand you have an in-app purchase for YouTube Premium, but it doesn't reflect the update of being a premium member in the app. We can help point you in the right direction.

We recommend to contact the app developer for YouTube for additional assistance. Here's a helpful article on how to contact an app developer: How to contact an app developer

In addition, here's two additional articles for support by YouTube:

1. Get support for YouTube Paid Products
2. Troubleshoot YouTube Premium member benefits

Best regards.
