Map graphics disappear when sharing it as a web map.

[AlexBohler]

I'm trying to share a map I've made in ArcGIS pro as a web map for a class. However, I'm getting this  "layer's symbology will be downgraded" message, as well as a "unique numeric IDS are not assigned" message. I believe I can resolve the second error by auto-assigning, but the other I don't know how to fix. The map uploads successfully, but when I open it in the Arcgis Desktop map viewer, my arrows are gone and the text is out of place. My graphics are simple and only use text and arrow features that are part of Arcgis Pro, so I'm not sure where the issue is. Any help would be greatly appreciated!
