You are sharing a web scene layer or a web scene that contains layers with vertical coordinate systems that do not match the scene's vertical coordinate system. There is no transformation between at least one of your layer's vertical coordinate systems and the scene's vertical coordinate system.
Solutions
- Do nothing. All vertical coordinate systems will be dropped, and the scene or layer will be shared.
More information
Without a valid transformation between vertical coordinate systems, there will be a shift in your data. To avoid a shift, all vertical coordinate systems will be dropped.
