I have tried to load an existing Operations Dashboard in the Dashboards Beta and the images which were usually shown for features on the map do not show in the details block when media is enabled. We use media instead of enabling attachments as this was used to show a larger attachment from the features in the map.
We are now strictly enforcing http(s) in the Beta for all links to images and other media. Can you check that the underlying image points to an http(s) resource?
If they are tied to an AGOL hosted service, they should be https. Is there any way you could provide me a link to a service or dashboard? I would be happy to take a look.
You can also direct message me a link.
I'm seeing the same issue with Attachments not showing up when the Media option is on in the Details element. Operations Dashboard is fine, same hosted feature and attachment in Dashboards (Beta) and I get nothing... I also notice the Attachment option shows a link in Operations Dashboard and a thumbnail in Dashboards (Beta). I hope if i have Media and Attachments enable I wont end up with two images in the Details element?
Update to all reading. We have been able to reproduce the issue and it is known by the dev team. Will update this thread when the fix makes it into a release!
It appears that in certain cases media/attachments are not displaying. We also have an issue where media does not show as expected when enabled in the beta.
We are always trying to figure out what should be implemented next so that user's get the most value out of Dashboard. The best thing you can do is upvote that ArcGIS Idea and add a comment with your usecase to the thread.
Have a great day Will!
