Hey @alex.miranker - welcome to the Tulip Community!
Thanks for sharing your question. You shouldn’t need to have the embedded barcode scanner widget in your app (this is the one integrated with you computer webcam) if you want to use the custom barcode scanner. Instead, you should just be able to use the device trigger for the barcode scanner you set up, and thats it!
If you delete the embedded barcode scanner, does this take care of the problem? Or is there a reason you would want both the custom barcode scanner and built-in webcam barcode reader both to run at the same time?
