@grishka Yes, "Dieser Artikel ist nicht verfügbar." means "This item is not available."
On the Google Play website, it says "This app isn't available for your device", though.
I had the same thing with #SchildiChat (https://schildi.chat/) - a matrix client a while back, maybe someone from there knows what the issue was.
Benjamin 👨🏻💻🕊, that's strange. I've double checked that the only requirements are a touchscreen and Android 6.0 (or newer). Google Play is sometimes sneaky with this stuff, like it thinks your app requires that the device has a camera if you declare permission to use the camera.
