Did IAP fails when it Tested Multiple Times?

Hi All

I am working in Code less Unity IAP. Where i am using subscription. it is working fine and Good. But

when i am doing testing a Subscription Mulitiple Times. 10 out of 4 times. IAP Plugin is calling

OnPurchaseFailed.

Once again if installed through xcode. It is working fine and Good.

My Question is If i test subscription multiple times. Will IAP works fine or it will create problems.

Is there any Solution for this problems.

Thanks in Advance…

Generally you can only purchase a subscription once. Please show the output of your debugging during your testing, and the device logs.
