According to here:
Under the “data formats at a glance” section, I see that GeoJSON has a check mark under 3dTiles as compatible format for an asset type. I tried loading some GeoJSON in Ion the other day but have not been able to get this to work. Are there any caveats I am missing? If so I feel they should be listed for each data format and asset type since this does not seem to be well documented. Thanks in advance!
