I am trying to create a web scene from ArcGIS Pro to ArcGIS Online. However, I am running into a lot of issues, the most annoying one being that I am running into a very vague warning. Through using the Share tab to share the scene as a web scene and then analyzing it, I am able to get the ERRORS to 0 and the WARNINGS to 1, but the warning is a very vague warning that reads Warning 24080: Ensure scene is authored correctly before sharing. The solution points to how to author a web scene, which gives some things to avoid doing. I went through very carefully and reviewed everything step there, and even watered down my scene to something that isn't very useful for my purposes, but just to get something to actually go through, and still no luck. When I try running any web scene to ArcGIS Online from ArcGIS Pro the process will fail. On ArcGIS Online the WFL will show up, but it will be empty. I have no idea what is going wrong with this.

Ultimately I would like to bring a 3D web scene into ArcGIS Online from ArcGIS Pro, but I cant even get a very basic 2D scene to publish. Has anyone found a solution to this problem? Currently I have to create KML features to get anything over to ArcGIS Online, and even then, it is not recognized in the ArcGIS Online scene viewer. The whole intent of the project I am working on is to produce 3D models on ArcGIS Online to be able to share it with a larger audience than keeping it on ArcGIS Pro on the desktop could provide. I have created some web pages using WebGL, ArcGIS v3, ArcGIS v4 Beta, Cesium, and Google Earth APIs with JavaScipt to see how well one of these workarounds would do, but they are a lot of work and they are not as easily integrated with creating story maps from ArcGIS Online in the future.

Recap: Looking for a way to bring my 3D scene in ArcGIS Pro to ArcGIS Online as a web scene. Share As Web Scene in ArcGIS Pro is not working for me, and I cant figure out why. I would love to hear and suggestions or solutions to this issue.

EDIT: I am not using multipatch features, extrusions, feature classes with over 2000 features, or 3D symbology. My scene is in global mode as well. As you can see my scene is not very advanced, and even though I want 3D extrusions of the buildings I am not even able to get a scene without 3D Properties to publish.
