Expected Behavior

Snapprefs dev build should work with Snapchat 9.39.5

Current Behavior

No features is currently working on Bluestack with Xposed framework on Snapchat 9.39.5
It was totally working with Snapprefs 2.0.0 beta and Snapchat 9.31.1
I don't know if it can help but when I run for the first time Snapprefs, a message displayed : Registration with Web server failed

Steps to Reproduce (for bugs)

Get a Bluestack PreRooted and install Xposed Framework with BStweaker
Install Snapchat 9.39.5 and Snapprefs from the artefact on Jenkins
Try to make it work Snapprefs
See the Xposed logs:
