Clear browser cache after a Mosaic upgrade

The following improvement was introduced in Mosaic 20.1.0.0.
​
Javascript and CSS resources in the Mosaic code base are now versioned with each release. This means it is no longer necessary to clear the browser cache when changing Mosaic versions.
​
However, customers have reported in recent versions they are required to clear the browser cache manually in order for screens to render as expected.
​
This has been raised with our Development Team for investigation. In order to assist with the troubleshooting, they've suggested using the browser tools F12 to check for any errors on the console. It's possible there could be an issue with webpack bundles and are interested in any errors relating to this or other components.

Please update your support case with details of any errors identified. We will continue to keep this article updated as our investigation progresses.
