I'm trying to update a purchasableId against a line item (eg if the variant changes) via a custom module/controller (long story short native controller is not updating options stored against against the line item since upgrading to Craft 3).
If I look at the record in the database the purchasableId is updated but the value in the snapshot does not. On a second save it is.
The cart object references the version in the snapshot - how do I update the snapshot as part of my code so that the cart object shows the correct/intended value?
$lineItem->purchasableId = $purchasableId; Commerce::getInstance()->getLineItems()->saveLineItem($lineItem, false);
