OK its probably a Ludei issue.....
and its probably a issue of ludei server that don't manage IAP, infact I found a discussion on the ludei dev portal that I link here:
http://support.ludei.com/hc/communities ... cale=en-us
and this is the part that I think is interesting:
"second - I fixed the purchasing process (by a workarround)
This might help others:
You do NOT want to use „managed“ mode! Just implement the onProductPurchaseVerificationRequestReceived, take the productId and store it somewhere on your own with localstorage (implement some security, so that the storage cannot be manipulated).
That will save you a lot of troubles!
Why:
There are server errors on the ludei backend
You won’t get restorePurchases to work properly, because you will not receive a proper purchase item
I cannot post more infos right now - this is too complex to write."
At this point I think we should try to set Store Modo UNMANAGED...
but I do not know how to follow the steps described above....
