Cannot access free audiobooks

[AYC55]

I have a premium account which should include 15 hours per month free audiobooks. but when I go to audiobooks, they all have a padlock sign. My friend has same account and sees the same titles but saying “included in premium”. I am the account manager, not an invited extra person.

I have exactly the same - I am the plan manager and when I check it says I have used <1 of my hours of free audiobook listening, but then when i go onto any audiobook it has a padlock and asks me to purchase it? WHY IS THIS
