It seems I'm unable to change the GTIN of my items via Squarespace. Because of this, I'm receiving disapproved or invalid as I'm unable to update UPC codes raw data. Every 8 hrs, Squarespace is changing the UPC (ID) that I manually update via Google Merchant center back to a random generated ID (example - 0a15434f-89cb-4109-9eca-5284c8ac144c).
Anyone else using Google Merchant Center that's has a work around for this issue? I'm unable to find where to update this item ID in Square to the actual UPC code of the item so Google accepts it.
