Script execution conflict causing Intercom Messenger to fail on mobile web views

Hi everyone,

I’ve been working on integrating the Intercom Messenger into a custom web application, and I’ve run into a specific technical hurdle that I’m hoping the community can help with.

I am currently using a delta vietnam setup to execute some background scripts and handle task automation within the site's environment. While everything works perfectly on the desktop version, I’ve noticed that when this executor is active in a mobile web view, the Intercom Messenger launcher fails to initialize. It seems like there might be a conflict between how the script executor manages the DOM and the window.Intercom boot sequence.

I’m seeing a couple of related issues as well:

I'm not sure if the asynchronous loading of the script executor is competing for resources with the Intercom snippet, or if it's potentially masking the user identity variables needed for a successful boot. Has anyone else used a delta vietnam community workflow or a similar third-party script manager alongside the Intercom JavaScript API?

I’m trying to figure out if there is a way to "delay" the initialization of the executor until after the Messenger has successfully loaded, or if I need to move the Intercom boot code to a specific lifecycle event to avoid this overlap. I really value the functionality this setup provides, but keeping the chat open for my mobile users is a priority.

I’d love to hear if any developers here have dealt with similar script execution conflicts!

Hey ​@yuri889

To reduce conflicts, I’d suggest:

  1. Include the Intercom snippet and your window.intercomSettings before the executor script. Boot Intercom first, then initialize the executor.
  2. Wrap your executor startup in a page‑load handler so it only runs after the Messenger has had a chance to load, for example: 
    function initExecutor() {
      // your executor initialization
    }

    window.addEventListener('load', initExecutor);
  3. On mobile, confirm that:
    • window.Intercom is still a function after the executor loads.
    • window.intercomSettings still contains your app ID and user identity.

If this is actually running inside a native app webview, it’s worth knowing that Intercom officially recommends the mobile SDKs (iOS/Android/React Native) for in‑app experiences, and the web Messenger for standard desktop + mobile browsers; webviews can work but are more prone to exactly these kinds of JS conflicts.
