Why Amazon is putting a hold on the funds from my sellings?

Why Amazon is putting a hold on the funds from my sellings?
I have a great selling history. When will Amazon stop holding my funds?

Thank you!

As a new seller who registered to sell on Amazon on or after 15th August 2016, you are subject to the Estimated Delivery date reserve.

The money you make from a sale will be held in your account for at least 7 days after the estimated delivery date of each order. Then, it will be added to your available balance and disbursed at your next scheduled settlement date (usually takes 2 weeks).

Unfortunately, this is a permanent feature.

Here it is explained in a picture:

The only way how to speed up the process is shipping using Amazon’s integrated carriers. More information can be found on this link:
