Square for WooCommerce 5.3.3 adds a new Woo Admin dashboard notice that alerts you when your WooCommerce product catalog hasn’t synced with Square recently, so you can catch issues before they affect inventory.
This release also prevents duplicate Square catalog items when a product SKU already exists, and stops unmatched variations from overwriting unrelated products during sync.Inventory pushes now fall back to SKU-based lookups when a Square variation ID is missing, so stock updates go through even when the connection between products isn’t perfect.
Syncs no longer stall on malformed Square catalog data, and removing payment tokens on staging sites won’t accidentally disable live cards.
