Can't install Samsung Smart Switch

I want to install Samsung Smart Switch on my Samsung Galaxy M30S SM-M307FN. The requirements according to the Smart Switch website are > ### Which devices support Smart Switch? > > Phone/Tablet: Android OS version 4.3 or later But the install fails:

> adb install "Samsung Smart Switch Mobile_3.7.60.1.apk"
* daemon not running; starting now at tcp:5037

Performing Streamed Install
adb: failed to install Samsung Smart Switch Mobile_3.7.60.1.apk: Failure [INSTALL_FAILED_BLOCKED_CROSS_DOWN: INSTALL_FAILED_BLOCKED_CROSS_DOWN]

It seems the Samsung Device Protection Manager blocks the installation with _FAILED CROSSDOWN for sep lite_. What does that mean? ![Detail section of the Google Playstore app for 'Samsung Smart Switch Mobile' ][4] The compability section in the playstore says *Android 5.0 and up* required, but the device is on Android 11. Also it says *Compability: Won't work on your device*. Why is that?
