My User Dashboard shows my users Browser info as false or as Other 0.0.0 / Other 0.0.0.
How does Auth0 parse the userAgent? I am overriding my chrome version to show my app version in my user agent. This works just fine in Google Analytics and Intercom.
As you mentioned the browser information shown by the Dashboard is indeed parsed from the raw user agent information available from the logs. Given you modified the user agent string the parsing is failing to identify the browser, however, you should be able to still obtain the raw user agent information directly from logs and in this way obtain the desired information.
You can use the /api/v2/logs endpoint and explicitly specify the user_agentfield as one of the fields to be included for retrieval as part of the fields parameter (also implies that include_fields=true).
