The settings are set to show all apps, and I found and successfully downloaded and installed all other apps I needed from the App Lounge (such as Signal, ProtonMail, Spotify, etc)
I also downloaded Aurora Store, and the app also does not show there.
I am having a similar issue.I have a Murena Fairphone 4 running e/os for about 2 years. Generally no issues, but lately I can’t find several apps in App Lounge. Running android 12 e/os 1.14 system says it is the latest, but concerned the listed date is 16 Aug 23. My App Lounge version 2.5.9 has location and IP exposed, anonymous with all apps set to show. I have a warning that if I don’t update Signal in the next 2 days it will stop working. Can no longer find Signal, but a result loads as ‘unknown’, can’t do anything with it. Also want the Skoda app, get similar problem
