AZInsight runs many processes in the background when the stock checker feature is running. If you see products being left behind in the shopping cart, please try the following:
1. Make sure you are running the current version of AZInsight.
2. Disable other stock checker extensions as they might be conflicting with AZInsight and essentially running the same type of functions in the background.
3. Ensure you are on an internet connection greater than 1MB download speed or with at least 3 or more bars on the WIFI connection.
4. Remove AZInsight and reinstall it.
