Empty list on Oreo

Running v1.7 from f-droid on my Magisk rooted Oreo 8.0 phone with root granted to the app but an empty list is displayed. If I use a root file manager then I can parse WifiConfigStore.xml and get the details manually. Are any logs generated to troubleshoot?

I am a bit confused what app you actually running. Wifi Key View from evait security is not available on F-Droid Market.

My bad, it is hosted on Izzy's F-Droid repository: https://apt.izzysoft.de/fdroid/index/apk/wkv.android.evait.com.wifikeyview

So it is a direct link to your prebuilt APK. Can you confirm the issue?

[FLX-0x00]

We can not confirm your issue. Our Oreo test device works fine. The file is used in: https://github.com/evait-security/android-wifi-key-view/blob/ae1fabd89bee1ce409322e7dba2fbeec9f357433/app/src/main/java/wkv/android/evait/com/wifikeyview/MainActivity.java#L122

Have you tested it on a real Oreo 8.0 device? Here is a logcat:

You can clearly see an error, even though superuser access has been granted:
