ITunes Connect: is it not suitable for marketing incentives?

Question

I use auto-renewable iap in my application, but recently I received mail from iTunes Connect, which I really don't understand.

This is a notification notice to inform you that although your recently sent app, xxxxx (app name), includes renewable subscriptions for in-app purchases, it is not eligible for marketing promotion.

As a result, iTunes Connect will turn off the marketing promotion option, and you will not be able to offer free extensions for automatically renewed In-App Purchases in exchange for the right to send marketing materials.

I set the IAP auto-renewal period to 1 month and 7 days for free, does this mean that 7 days will be deleted for free or what will affect the automatic renewal of IAP?

Thanks in advance.

In the document here they say:
