Some issues can be specific to a user, and may be difficult to troubleshoot without more detailed information. Console logs help debug issues by giving us insights into error messages that get documented by your browser.

NOTE: This article is only for mobile iOS devices (iPhone/iPad). To document the logs from a Chrome browser on your Desktop (PC/Mac) follow this article.

Steps

1. Follow the steps to collect the console logs.
2. Please take screenshots on the device following these instructions by Apple.
3. Provide those screenshots as an attachment on your support request.

Collect console logs on iOS device

Enable JavaScript log collection by navigating to chrome://inspect in Chrome for iOS and leaving that tab open to collect logs.

In another tab, reproduce the case for which you are interested.

Then switch back to the chrome://inspect tab to view the collected logs.  

Important: (Log collection will stop if the chrome://inspect page closes or navigates and logs will be lost as they are not persisted.)
