Bug 443803

SUMMARY

Maybe this is partially related to this bug: https://bugs.kde.org/show_bug.cgi?id=443802

When I open Discover the Snap app list never gets downloaded on Neon, even if it's set as default. 

STEPS TO REPRODUCE
1. Open Discover on KDE Neon
2. Click on any category (like accessibility)

OBSERVED RESULT

No Snaps are loaded, even if you give it a long time.

EXPECTED RESULT

The Snap list should be download and cached so it has the list ready the next time Discover is restarted. Maybe it would be good to have a GUI to graphically update the list manually.
