I use LNM for flight planning.

I just switched from X-Plane 11 to Microsoft Flight Simulator 2020.

I'm not seeing the ground elevation in the Flight Plan Elevation Profile window.

It shows the flight planned altitudes, Navaids, TOC & TOD.

Any suggestion how to correct that issue?

I suppose you're still using the buggy online elevation data.

Go to "Options" on page "Cache and Files" to install the offline elevation data (https://www.littlenavmap.org/manuals/littlenavmap/release/2.4/en/OPTIONS.html#cache-elevation)

The online elevation data does not cover the whole world.
