Extensions API version: 2026-01 Description Both shopify.productSearch.searchProducts() and shopify.productSearch.fetchProductWithId() silently fail at the same time on certain devices, while the native Shopify POS search bar continues to work correctly for the same products. What we observed In …

Hi @Gunes , you’ve noted this happens on certain devices only. Can you share more information on that so we can investigate further?

hey @Paige-Shopify :slight_smile: yes, it only happens in this one cafe and no other locations so far. device details: model: Air 13-inch (M2) (Wi-Fi) os: iPadOS 26.3 (23D127) shopify app: 11.0.0 connections tab the connections tab during one of the incidents, photo taken by the barista [Unti…

hey @Paige-Shopify , I added a diagnostics screen yesterday, I have some more info. [Screenshot 2026-03-04 at 11.25.43] As predicted product.variants.length is 1, but product.numVariants is 12.

Perfect, thanks for that extra context. Just to make sure, is this happening consistently or sometimes?

It’s happening sometimes and not consistently. I’ve also now deployed a workaround/test-fix to “refetch” the variants with fetchProductVariantsWithProductId, if the variants.length does not match numVariants but i dont know if this explicit call will work or not as fetchProductWithId already suppos…

hey @Paige-Shopify , thanks for the info. As I’ve written earlier I’m already using the fetchProductVariantsWithProductId(id) as a fallback if and when the fetchProductWithId(id) does not return full variants. But the funny thing is, it does almost always. This expectation is also stated in the doc…

Just to add some extra info, another report came in from a barista today. In the component, I’m using the scanner to get the barcode, then I’m using const results = await shopify.productSearch.searchProducts({ queryString: barcodeString }) [IMG_5035] You can see that the scan data is there an…

I believe this is the same issue that we reported last year and it’s begun to recur recently: Ongoing Data Synchronization issues affecting POS ProductSearch API
