Hi,
when I add an item to register app I receive intent two time
at first with orderId,lineItem and itemId not null(all of them) the second intent with same orderId but lineItemId different and null itemId. like this :
orderId: 7N710ST1YYKM2 lineItemId: XN1RB6K1XC9M2 itemId: GNJ18T6Z5R0ZM
orderId: 7N710ST1YYKM2 lineItemId: 4CNED11SASGN0 itemId: null
as you can see lineItemId change
