I use sandbox to test subscription payment for my store, I set up a recurring payment on daily basis on 15th, the first and the second payment were all successful, they were processed on 15th and 16th, but later, until 20th there was no more payment go through, however I see the payment detail still write that the next payment due 17th. I cancelled this payment and set another one one 20th, the first payment was successful, but until now (22th), my second payment was still not processed. can anyone tell me what's wrong?
