When a capture is completed, the completion screen appears and the upload starts. Ensure that you have access to a good internet connection before the upload is begun.
The app throws an error (screenshot below) if your internet connection is not strong enough. Switch to a better connection (preferably Wi-Fi) and the warning should disappear by itself.
Important:
The upload happens in the background, if you start scanning another SKU after completing one, there is no limit in the number of uploads that can happen in the background.
For a faster upload experience, the app screen should be kept open. If you minimize the app, the upload process might happen slower than usual.
Please do not kill the app until your uploads are finished, it will pause the upload process and might lead to a failed upload
The app automatically clears its files from the device used for capture after the upload is successful
