Intercom Fails After Login Without Reload

[nguyentoanit]

We are experiencing a critical issue with Intercom integration in our web application.

After a user logs in without a full page reload, the Intercom widget appears and lists existing conversations. However:

• Existing conversations cannot be opened
• Creating a new message often fails
• Network tab shows intermittent 403 Forbidden errors with the message: “App suspended”
• • Specifically on requests to: POST /messenger/web/conversations/:id

If the user reloads the page after login, everything works as expected:

• Conversations open normally
• New messages are sent successfully

Context:

• We are using the react-use-intercom package for frontend integration.
• The app performs a soft reboot after login (without reloading the browser tab). Call shutdown and boot with intercomUserJwt then
• When I had this issue it was always because the app_id passed was 'undefined'

We are unsure whether this issue originates from the react-use-intercom package or from Intercom itself.
If you have any suggestions on how to fix this problem, kindly let me know.
