Hi @SugajanSrinath,
Thanks for reaching out to the community forum. I'm sorry to hear you've had such a frustrating experience with your YouTube Premium account and your Nest speaker. I understand connecting your YouTube Premium account to your Nest speaker is really necessary, as you want to listen to music without ads. Don't worry, let's work together to get this fixed.
Can you tell me what type of Nest speaker you have? To check, please visit the following article: Google Nest speakers and displays.
Please make sure your Nest speaker is linked to the same account as your YouTube Premium account. Also, check if you have YouTube as your music service provider. If so, delete it and try to re-add it. For more information, check out the following article: Link your music services and set your default service.
I appreciate your troubleshooting efforts and sorry for any inconveniences caused. Let me know how it goes after trying these steps. I'm happy to assist further if needed.
Sincerely,
Jonathan
