Hey there,

I am really sorry for the delay of this reply as it is a weekend for us here.

Can you check my following explanation and see whether I understand your current requirement correctly?

1. Let just said the subscription period 1 year.
2. About your drip schedule of content :
-> Part 1 - blablabla (release on 5/5/2019)
-> Part 2 - blablabla (release on 12/5/2019)
-> Part 3 - blablabla (release on 19/5/2019)
-> Part 4 - blablabla (release on 26/5/2019)
-> Part 5 - blablabla (release on 2/6/2019)
3. Even the user subscription license still active, they still unable to read those content if haven't release right?
4. Let said if the Part 1 already released, so this user only can access this content for 1 week only, after 1 week, this user unable to access this Part 1 anymore even his subscription license still active?
