Hello,
I'm a little bit confused about last non-published builds from snapprefs build website, wich version of snapchat is supported by it ?
Since Snapchat devs have considerably accelerate the updates of snapchat, i know that the last build of snapprefs wouldn't support it, but i will can use again this app when the nougat's xposed framework updates will be done.
Instead of just installing development builds and not reading what the developers post about them you should probably either (a) stick to the officially released builds or (b) make sure to read where the devs mention important information about them, such as stating pretty clearly that the latest 'update' branch is NOT WORKING YET. MaaarZ only started updating the code but none of the features are expected to work.
You don't even have to read a whole lot to find it, just go back 4-5 pages and you'll see where comments about build #40 started popping up and where the devs replied to them with what's going on.
