Hey GeoNet,
I am using ArcGIS Pro 2.0. When I try to add the Bing Aerial basemap that I have (licensed and am able to use) in a Map within Pro, the basemap adds with the red exclamation mark indicating a broken link. In ArcGIS for Desktop 10.5 and Portal for ArcGIS 10.3, this Bing Aerial basemap is able to be used without an issue. Has anyone encountered a similar issue or have any suggestions? Thanks so much!
