IE11 is no longer supported in Clarity 16.0.1 but the option remains in System Options, so it should be expected to work or the option should be removed.
When unchecked, the 'Hide IE11 Not Supported Banner' option does not produce a banner to the end-user.
Steps to Reproduce:
Expected Results: The option should be removed as it is no longer required.
Actual Results: The option is available and the user is expecting a banner to be displayed, however the banner is NOT displayed.
Example of the banner working in previous releases:
A Toast Message appears - 'Internet Explorer 11 is not supported. For the best experience, use a supported browser.'
Release : 16.0, 16.0.1, 16.0.2
This is DE64788, fixed in 16.0.3
Workaround: Use supported browsers
