The above suggests you may be able to get it fixed under your warranty when you have enough time to do so.

Go to the nearest Apple Store to you now, or Apple Authorized Service Provider, with proof of purchase and your identification. See what your options are while within that 14-day purchase window, even though you purchased it while travelling. They may have a comparable unit in local inventory, may be able to fix it, or yes, you may be waiting for a build to order replacement.

Oh well then that’s no issue then. I would advise making a return / exchange under warranty as soon as possible however.

With omicron, I will bet that the Apple Stores are now requiring reservations only to get into the Store.
