When opening the navigation tab and zooming into a star system, it doesn’t show the sector map, but instead this text: ‘Navigation Data Downloading’
I tried waiting for it to download, hopping to different systems using /navroute command, restarting app but to no avail.
Strangely enough, reinstalling the app fixes the issue BUT the problem re appears when you close and then reopen the app.
Device- iPad pro 5th gen
No plugins were installed.

Thanks for the report, we'll push a fix for this shortly.

This has now been patched.
