Patching shipping data does not work

[vovkin]

We implemented patching order data when customer cancels payment, change something in order, and then starts payment again.

At first we had patching for order price only, and that worked fine. Now we need to patch shipping data as well. It was implemented according to documentation (https://developer.paypal.com/docs/api/orders/v2/#orders_patch), to update shipping/name and shipping/address separately. Request looks correct, and we also get correct response from PayPal API (204 code). But the problem is that shipping address stays unchanged, so it's the same as when order was created.

Interesting though that price patching still works fine.

Is it known bug, or documentation is misleading, or it's a sandbox thing only? Can somebody help me here please, I've spent q sometime implementing shipping data pathing, and don't want to throw it away.
