I have Skype for Business running on Android 8.1.0. The OS is LineageOS 15.1 installed from an unlocked bootloader. The ROM is not rooted, and I have not enabled root access. When I open the app it says "This app can't be used because you are using a rooted device. Contact your IT administrator for help." I have tried disabling ADB and developer options, but neither of these seem to make a difference.
How does the app check for root access, and is there a trick to get the app to recognize the device is not rooted?
