Intercom Messenger widget failing to initialize on single-page application route transitions


Hello everyone, I have been working on integrating the Intercom Web Messenger into our web platform, but we are experiencing unexpected behavior during dynamic page transitions. Specifically, the chat launcher periodically fails to mount or becomes unresponsive after navigating between client-side routes, forcing users to perform a full page refresh before the widget becomes functional again.

We first detected these intermittent display glitches while troubleshooting identity verification and event logging on the website, where custom user attributes appear to delay script execution. Has anyone faced similar timing or lifecycle issues with the JavaScript SDK in single-page environments, and what is the best practice for cleanly updating or re-booting the Messenger instance across route changes?
