Client troubleshooting

Some issues can be specific to a user, and may be difficult to troubleshoot without more detailed information. The developer console is a tool which logs the information associated with a web page, such as JavaScript, network requests, and security errors. Console logs help debug issues by giving insights into error messages that get documented by your browser.

If your issue is still happening, please help us capture the console logs for the error by performing the following steps. The following are instructions for how to open the developer console on various different browsers.

Once you have located the console, please send us a screenshot or export its contents to a plain log file using the “export” or “Save As” options (right-click).

Then, extract the compressed file to a directory of your choice. The extracted folder contains a logcat. Logcat is a command line tool that writes in a file the system messages, including the errors and messages generated by the application. Open a terminal and execute the adb file:


When this is done, connect the Android device to the PC and select “File transfer” in the connection options:


Next, enable the developer options in the mobile device. This is usually done by tapping several times in the Build Number. Then go to Developer options and enable USB debugging.


Finally, allow USB debugging for the PC.
