Well, you are right about the audience, many people might prefer to downgrade to older versions. However, support of older versions will significantly complicate the development.

The app uses several APIs that are not available on older versions. In one moment in time when I had the support of lower versions the app consisted of many wrappers for OS API versions. It was a challenge to support and add new features to such a codebase.

Plus even Android 11 already reached end-of-life support https://endoflife.date/android.

Technically it's not impossible, so I might consider adding it in future.

Out of curiosity, which API are you using, not available in Android 9 / API_LEVEL_28?

I just checked all APIs/Libs that the app uses had declared support of API_LEVEL_28, but have recommended a higher target (above 30). My bad. I assumed this modern Material 3 Compose had hard API-level requirements.
