Google One Downgraded My YouTube Premium to Premium Lite

Even though I have a Google One subscription, I need assistance with an issue involving YouTube. I purchased Google One primarily to use Gemini Pro, but I later realized that the plan also includes YouTube Premium Lite. Before subscribing to Google One, I had a separate YouTube Premium subscription and enjoyed the full Premium experience.

After activating my Google One plan, my existing YouTube Premium subscription was automatically downgraded to YouTube Premium Lite. Since then, I have been unable to subscribe separately to the full version of YouTube Premium. As a result, I am seeing ads again and can no longer enjoy the complete Premium features that I previously paid for.

I use YouTube on both my iPhone and my Windows PC, and the same issue occurs on both platforms. I contacted Google Support by email to explain the situation, but I have not received a response yet.

I would like to keep my Google One subscription while also being able to subscribe separately to the full version of YouTube Premium, just as I could before. I respectfully request that the Premium Lite restriction be removed from my account, that my case be reviewed, and that my account be restored so I can once again use the full YouTube Premium service.
