Return Timeframe for Exchange Orders: when does it start counting?

You might be wondering when exactly does the return timeframe start counting? And that's a pretty good question.
To give it a proper answer - the time starts ticking from the moment the exchange order is
  • delivered.
  • or placed. This is a fallback in case your fulfillment does not store the delivery date on the Shopify order.
  • Note that this is the delivery date (or order date) of the exchange order, not the original order.
