Apparently the RVS 2.0 is not compatible with receipts generated by the 1.0 Unity Plugin. Receipt validation fails with a BAD_REQUEST (400) error in this case. However validation using the RVS 1.0 still works. @Amazon: Could you please confirm the above? Can you guarantee that RVS 1.0 will be working until an new Unity plugin is available?
