Tried different browsers, same result. I am using Portal 10.3 also.
HI,
Esri Maps for SharePoint 3.0.1 was released at October 2013.
So, I would guess that Portal 10.3 is not yet supported.
If anyone has further details, please correct me if I'm wrong.
Regards
Thomas
Portal 10.3 is supported.
Hello Everyone,
A spinning wheel can be caused by multiple issues, but there are a couple of common ones.
The most important thing is to add the entirety of the environment to your trusted sites list. Here is a Microsoft Article on how to add stuff to your trusted sites list:
Security zones: adding or removing websites - Windows Help
I suggest you add the following:
http://<YourSharepointSite>
http://<YourPortalSite>/<WebAdaptor> << if applicable
Thanks-
Justin
