Snapchat has implemented SafetyNet to its app, which need a special root to access Snapchat, so to access Snapchat:
**WARNING** Your warranty is now void when rooting your phone/tablet! Backup your everything using TWRP cause I am not responsible for anything wrong happens to your device!
* Download your device stock/custom boot.img (kernel) without SuperSU mod
and download UnSU.zip
from the amazing @osm0sis
* Flash UnSu.zip
and Flash stock boot.img
* Flash Magisk
* Uninstall Xposed Temporary and Login to Snapchat and install Xposed again OR use Root Switch APK from amazing Corner23 to turn off Xposed with a soft reboot and enable it again with another soft reboot (You Shouldn't use Systemless Xposed, you should use the official one from amazing @rovo89
or the custom one for samsung devices from the amazing @wanam
) [Note for Geeks: Wanam Custom Xposed can work on all devices whether Odexed or DeOdexed while Rovo's Official Xposed can work only on AOSP DeOdexed ROMs.]
* To know if you can login to Snapchat, download any SafetyNet Checker from Play Store and you should pass SafetyNet if everything was done correctly else you might have some residual files that detect that you used root before so you might need to start from beginning with stock ROM.
Hope it helps!
