IAmABadPirate_69 I'm just curious why the Craigslist app is not compatible with Graphene.
Some developers have bought into Google's idea that it is safer to restrict their apps to devices running a version of Android that has been certified by Google (even if it is very out-of-date). GrapheneOS is not certified by Google (and almost certainly never will be).
IAmABadPirate_69 I saw this post with the same question as me, but no real answer: https://discuss.grapheneos.org/d/15577-matterport-and-craigslist-app-not-available-on-your-device-help-appreciated
That is a real answer. Contacting Craigslist and asking them to fix their listing in the Google Play store (as the poster in that thread did with Matterport) is a way to move the issue forward.
