Every test run starts on a new container with a blank slate. Cookies from your application can affect training the test, causing a mismatch with the test environment. To best remedy this you can delete just the cookies for your app. Here's how to do that without losing all of your other browsing data or getting logged out of your favorite apps.
When you start a new test in mabl, you can easily clear the cookies on the URL you're testing. When the modal appears when you start training, select the "Clear cookies matching current URL."
Start by clicking on the three dots menu in the top right of Chrome. Then click Settings > Advanced Settings > Content Settings > Cookies > See all cookie and site data. Or, you can just copy and paste this link into your Chrome URL bar:
Search for your domain name, then select and delete the cookies associated with that site.
Once those are deleted, you can start training or editing your test without previous data causing interference.
