The latest riskminder-client.js does not retrieve User Agent information for the unsupported browsers. The newer User Hints API is not supported by all of these browsers because they are in transition stage.
In order to start showing User Agent information on the Opera browser, we would like to resolve the issue.
Release : 9.1SP4
The attached riskminder-client.js has the fix and it addresses the User Agent not captured in Opera Browser issue. If you need clarification please reach out to the support team.
