+## Source Maps Not Linked When Using Live Reload
+
+When you run your app with live reload (for example, `ionic cap run android -l` or `npx cap run ios -l`), the app loads files from your local dev server instead of the production build in your `www` folder. Stack traces from events captured during a live reload session reference the dev server's URLs, such as `http://192.168.x.x:8100/vendor.js`, which don't match the source maps generated from your production build.
+
+Because of this mismatch, source maps won't apply to events captured over live reload, and you may see an error like this when validating a release with `sentry-cli`:
+
+```
+Uploaded artifacts do not include entry: ~/vendor.js
+```
+
+To verify that your source maps are set up correctly, test against a production build instead of a live reload session:
+
+```bash
+ionic build --configuration=production
+npx cap sync
+```
+
+Then run the production build on your device or emulator and upload source maps from your `www` build output as usual.

 Session Replay does not work correctly with `@ionic/angular`, `@ionic/vue`, or `@ionic/react` version `8.7.1` or newer. Pin these packages to version `8.7.0` to capture session replays.
