Description
When the Mira Android app opens in-app WebView content (e.g., shop redirect flows), the user's live session token is appended to the URL as a query string parameter, and a persistent user identifier is included in the WebView's User-Agent header. Both are then transmitted to third-party web properties, referrer logs, and any JavaScript running in the WebView context.
