auto-renew package for subcriptions of app on App Store

Question

"We noticed that the different durations of your auto-renewable subscriptions were created as separate in-app purchase products, rather than as different durations within the same subscription group."

I got this notice when submit app on App Store. I dont really understand "separate" mean. Can I devide the packages into many duaration, and each duration has different content? Or the content must be similar between duration?

Thank you for your help

Answer 1

It sounds like they want you to group all subscriptions, granting users access to the same content but with different durations, into the same subscription group.
