Not all Apps shown in Android Auto

flanked

Hi everyone,
at first: thank you all for absolutely amazing work!
I struggle with Android auto at the moment. I‘d like all my apps there but some just won’t show up.
Current problem: Threema Libre. Installed via F-Droid Store. I enabled untrusted sources in the android auto developer options. That already shows up signal and Spotify now, still no Threema libre. Any suggestions on where to look for some settings I might have missed?
Thank you

Try the following: Settings > Apps > Sandboxed Google Play > Android Auto > Android Auto Settings > Press 10x times on "Version" to enable developer mode and chose then "Customize Launcher". There you can add the apps. But there is no guarantee the App is probably working in Android Auto

ZoraIsHere I suppose this is about apps that do work but use a nonstandard app ID.

Not sure if you can unlock threema libre (as its purpose is to be the "non google version")

missing-root I think the best approach is try and error :D
