Magisk Manager app was removed from the Play Store for some odd reason(maybe Google didn’t like root apps) and you will need to now install it manually. But it is very easy to install, simply download the Magisk Manager APK file here and install.
Now, we do recommend getting the version 4.3.3 which has Magisk Hide feature while the newer version 5.0.1 beta on APKMirror.com is not recommended as it doesn’t have Magisk Hide feature and the beta version is not as good in our opinion.
With 4.3.3, you will be able to hide root by passing SafetyNet and allow you to easily enjoy apps like Snapchat or any Nintendo games like Pokemon Go/Super Mario Run. There is also Magisk Hide feature for individual app where you can hide root from individual apps for 2 layers of hiding root. Meanwhile, all of your rooted apps will work flawless. Also, Android Pay works just fine after you hide root, which is a benefit for Samsung users who lose Samsung Pay by rooting so you can keep using mobile payments.
