The Chromium 127 update coming in July 2024, affecting Google Chrome and Microsoft Edge, will remove mutation events. This will disrupt ArcGIS Enterprise portals in versions 11.2 and earlier. Users must either install patches that will be released by Esri to avoid issues such as blank navigation bars or upgrade to ArcGIS Enterprise 11.3. See the Portal for ArcGIS Application Display Patch page for more information on the status of patches for supported ArcGIS Enterprise versions.
What does this mean for you? You have two options:
You can install the patches released by Esri to ensure you do not lose functionality
You can upgrade your deployment to ArcGIS Enterprise 11.3
If additional time is needed, Google Chrome and Microsoft Edge will both support a new enterprise policy setting called MutationEventsEnabled that can be used to delay the effective date of this change. When enabling this setting, the change will not go into effect until Google Chrome 135 and Microsoft Edge 135. This will provide about nine additional months to either install the necessary patch or upgrade to a new version of ArcGIS Enterprise. Additionally, you can use the Firefox browser as an alternative to Google Chrome until you are able to update to an Enterprise version with the necessary patch.
