We received an email from Amazon (shown below) that says that sellers can now upgrade their Vine enrollment tier within 30 days of the enrollment in Vine. The email also refers the reader to a link in Seller Central that describes how the Vine program works in general.

However, in the Vine administration interface for sellers, there is no button to increase the tier of our recently enrolled products.

Additionally, the link to the Seller Central documentation provided by Amazon in the email makes no mention of how to upgrade the Vine enrollment tier for a product.

How does a seller upgrade their Vine enrollment tier in the way described in this email from Amazon?

I have sold hundreds of a particular product for a set FBA fee. Randomly, one day the FBA increased by 25%'ish.

I found that Amazon moved me from the small-standard sized tier to the large because the thickness of my package is .04 inches more than the allowed amount, so now they group my product with items that can weigh up to 20lbs. That's the size of a credit card receipt on thermal paper, two sheets of printer paper, or two business cards.

Package dimensions: 3.82 (L) X 2.8 (W) X 0.79 ( H) inches

Unit weight: 0.07 pounds

Product size tier: Large standard

Have any of you ever had success staying in the smaller tier when you are this close to the requirements?

I've been selling for 8 months via FBA, 750 orders, ODR 0%. According to Amazon Pay documentation I should automatically have been upgraded to Reserve Tier II. This last month I had $2.8k in account level reserve and get it paid out with a 2 week delay.

I created a case like documentation asks me here, providing:

- my merchant ID

- my business website URL

- my reason for requesting the upgrade (need cash for ordering new inventory

But a clearly AI response keeps on asking me to "elaborate your request in detail" or "we need more information to resolve your case".

What else do they want from me!?

PS: Also tried via Chat & Phone. Chat kept on having technical issues, and phone support has connection problems (can't possibly understand the words they are saying)
