IAP doesn't restore to some people

Hello everyone

We are currently experiencing some issues with IAP, some people that bought a non-consumable ítem long time ago is not restored, for people that just bought it works fine.

For people not working we are getting a PurchaseFailureReason DuplicateTransaction.



Thanks

 

Please provide steps to reproduce if you can. What version of IAP are you using? When do you receive the Duplicate Transaction error?

 

We are using IAP 2.0.3 and we get the error when the IAP try to restore

Is only the Restore functionality not working for this set of users? Do other purchases work OK? Is this on iOS or Android?

 

this is Android , purchasing is fine, the problem is the restore, some users didn't report any issue (users that bought recently), but users that bought it some time ago faced this error

 

Did you generate the log yourself (which means you can reproduce)? Also, I believe I know the what the issue is and which should be addressed in the next IAP release in a few weeks. Also, the IAP plugin version is located in the changelog file in Assets/Plugins/UnityPurchasing, 2.0.3 is the Package Manager version (confusing, we know)

 

The log is from one of my coworkers(we can reproduce it), specially in my case it works fine

the version then is: 1.21.0

 

Can you try with IAP 1.19 or 1.20? What is different between your configuration and your co-workers?

 

I'll try 1.20 and 1.19, but do you have the package for the 1.19?, I checked the sticky post of older versions but didn't find the 1.19

 

Please try with 1.20 and report your findings, however I suspect you will need to wait for the update regardless.

 

I'll try this and let you know what happened, Thanks for the time

 

Also, please try to determine what is different between the two devices that behave differently. I suspect the answer is in there.
