We have just updated 360 VR and are very happy to announce support for Web Scene pop-ups in 360 VR.
Getting pop-ups into 360 VR is very straightforward: if you have a Web Scene that has pop-ups and you create at 360 VR Experience, then your experience will automatically adopt these pop-ups and they will be clickable in the 360 VR web app. Try it out here - look for colored buildings and click on them:

Other notable improvements include a way to view 360 VR Experiences stored on a ArcGIS Enterprise portal and numerous bug fixes. For more information refer to the updated documentation.
