Hello OP here, I’m so sorry this is happening to you! Right now we haven’t had any issues recently, but one thing you can do is force close the shopify app to see if it will fix the problem. If not, check for shopify app updates or iPad updates.
If all else fails, use the iPad camera to scan barcodes as a last resort. You can do this by pressing the magnifying glass button that is top center of the pos screen, and on the right of the search bar there is a scan icon, press that and scan barcodes that way.
When you have time, completely disconnect socket mobile from the pos settings as well as in the iPad settings, then reconnect through the shopify pos.
Usually force closing the shopify app fixes most our issues now, but everyone once in awhile something weird happens and I have to go through some serious troubleshooting. Hopefully shopify’s team can foolproof the softwhere to where it doesn’t mess up as often.
