since this season I'm experiencing major problems with the terrain map and airport overlays.

I'm currently running version 4.0.0.397 on iPad mini 4 running iOS 15.8.3.

All is good in ground mode.

However in flight mode, terrain either won't update at all. Or it updates very sluggishly only some of the tiles. Attached you will find two screenshots from yesterday. They are taken 10s apart.

What sometimes does help (but not always): Running the app in the background and when you switch back to it, it will magically update everything.

Terrain maps might not seem a big issue, however I was experiencing this also with the approach and departure routes e.g. at LOIR.

Is this known to you? Any suggestions?

Regards

Benjamin
