There was an AIRAC update 20 April 2023 with a corresponding SD chart update. Later on the same day there was another SD South Africa chart update.

This latest chart does not display correctly at various different zoom levels. In particular in the Johannesburg area and to the south, although the fault can also be reproduced over most of SA.

As an area is zoomed in using the + selection the chart changes from topographical information to block squares. Continuing zooming or pinching can sometimes get the terrain data to appear, although not always.

Deleting and reinstalling the chart makes no difference. The terrain to the south of JNB is high and a fix soonest would be appreciated. Thank you.

I can't seem to reproduce this issue, could you post a screenshot?

It looks like SkyDemon is having issues rendering the terrain relief in the background. Could you try clearing the terrain relief cache? This can be done from Mapping -> Terrain, you should see the option near the top.

I cannot seem to find the relief cache. I am getting the same issue on iPad, iPhone and PC.
