shopify default variant sold out still selected
Defaulting to an unavailable variant makes Add to cart look broken. Fix variant defaults on top paid SKUs, then re-test mobile PDP.
The actual problem
PDP defaults to a sold-out variant so ATC fails until the shopper notices a different option.
Do this
- Open top PDPs; confirm default selected variant is purchasable.
- Theme logic: auto-select first available variant.
- Hide or disable OOS variant pills clearly on mobile.
- Re-test after inventory syncs from multi-location.
