I doubt that the forum mods you have tagged can actually action the extension. I'm not sure if there was a time limit for actually requesting an extension ? - maybe there was ? Did you actually receive an email offering the extension ? - because it looks like only those sellers who did get an email can request

I have just found this notification, so worth a try:

Dear Sellers,

UPDATE: THE FOLLOWING COMMUNICATION IS ONLY FOR SELLERS WHO RECIEVED THE EMAIL WITH AN EXTENSION PROPOSITION BUT HAVE NOT RECEIVED A RESPONSE TO THEIR REQUEST.

If you need to extend the DD7 policy exclusion until September 2025 for your Amazon seller account, please follow these steps:

1. Send an email request from your Amazon email address to eu-uk-reserve-policy-extension@amazon.co.uk

2. In the email, make sure to include your Merchant token. Your Merchant token is a unique identifier for your seller account, and it's essential to include it in the email for proper identification and processing of your request.

3. Once you've sent the email with your Merchant token, Amazon will review your request and provide further instructions or assistance as needed.

If you have any further questions or need assistance, please feel free to comment this post.

Thank you,

Julia
