Hi
Can you confirm that you are logged in to your site as a non-administrator user? (e.g. a subscriber)
The Intercom script is not shown to administrator users, or if you are not logged in.
If you still don’t see the Intercom button, please view source and see if the Intercom script is there (it’s a couple of lines of JavaScript with an “Intercom for WordPress | v1.0” comment before them).
If the script is in the source code, but the button is not showing, try the following:
1. Check that you have no ad blockers or privacy extensions running in your browser, as these can block Intercom.
2. Go to intercom.io and check secure mode is definitely enabled.
Let me know if that fixes it.
Cheers
Simon
