When is the exact expiration date of monthly in-app subscription?
If I start a subscription on, for example, Jan 31st, when will the first billing cycle end? Is it Feb 28th, or someday close but not 28th? What about leap years? [The official document][1] says If you cancel the subscription, the contract will last until the end of current billing cycle, which is about 30 days but varies a little depending on the months. But it doesn't mention the exact algorithm for calculating the end of each cycle.

Thank you.
