iOS auto-renew expired at the end of current subscription period

Question

I ordered a auto-renew product, After 5 minutes ,it become expired!

I think in Sandbox 5 minutes is equal to 1 month,

At the end of current subscription peroid(

Answer 1

In the sandbox environment, auto renewable subscriptions are much shorter than the actual time. From this answer:

   Actual duration      Sandbox duration
   1 week               3 minutes 
   1 month              5 minutes
   2 months             10 minutes 
   3 months             15 minutes 
   6 months             30 minutes 
   1 year               1 hour

And although this fact is not documented, according to some developers in Apple's developer forum (and my own experience), subscription will renew 5 times before you get 21006 error (subscription expired error). So if you have a 1 month subscription, it will be renewed every 5 minutes for 25 minutes. Don't rely on this fact though, as it's not officially documented and might change anytime.
