Can't search for Product Variant using the Variant's Barcode or SKU in POS App and also in Shopify

This query was raised in 2021. It is 2023 now and still this problem persists.

I have started re-organizing my entire brick-and-mortar store using shopify thinking that this is the best solution out there, but once I started using the POS,

this issue of manually selecting the variant arised and is slowing down the entire billing process.

Is the shopify support staff even useful or are we just posting queries in thin air.

This is really frustrating. Hope someone from support sees this and resolves this issue
