Topo Import from ESRI Terrain. It does not import anything!

Hi all!

I am trying to import a terrain using the Topo Import ESRI functionality.

I have an ESRI/ArcGIS Online dependent user Viewer type account provided by my organisation.

I have experimented with the Topo Import functionality of ORD and I managed to successfully import a terrain only the very first time.

After that time, ORD does not really import anything. It just creates a flat triangulated surface with 0 levels.

Has anyone else experienced this issue before and if yes has he/she managed to resolve the issue?

Could this issue be related to my ESRI account associated rights?

Any help will be much appreciated.
