I've tested v3 to v3.2 via fresh module installs and updates of other varying versions.
Module version 3.1 is the only one that works with edxposed on Pie/9 for me. It wasn't working with WiFi only so I had to turn off WiFi and use cell/data to get it working. After that it worked just on WiFi as well.
I'm using PSOP nightly bacon ROM on oneplus one and thunder kernel.
Previously, I was using carbonnrom 8.1 nightly with module 3.1 as well. V3.2 had address issues for me.
Update: Tried Bootleggers Pie rom for Bacon/OnePlus One. Version 3.1 works perfectly.
