App Lounge (sometimes) does not show/find all apps

if you run into timeouts, I think what you see is the cleanapk fallback:

Fallback when GPlay API or Cleanapk API isn’t available or times out in Categories, Search and Update tabs

(another reason for app-list returns to differ is how getAppFilterLevel()[1] behaves, for example with apps and geo-restrictions, but this is not what you post is about)
