I'm having issues using Operations Dashboard in a browser with ArcGIS for Portal. After creating a single pane view using a Portal web map, the link to open in a browser is not available. Is Operation Dashboard in a browser supported with ArcGIS for Portal 10.2.2 using Windows authentication?
The browser version of Operations Dashboard is only available in 10.3 Portal or above, and therefore it is not available in your 10.2.2 Portal. To get access to your views from the browser Dashboard, please upgrade your Portal and Operations Dashboard to 10.3. Once the upgrade is done, you should be able to access your existing single-display operation views immediately from browser Dashboard without additional work.
