This should fix your issue.
Use titanium backup, find snapchat, backup app and data. When you want to reinstall, just restore app and data. If you need more explanation, let me know and I can take screenshots and give a more detailed description of the process.
Linkme: Titanium backup
Edit- Actually, I don't think the linkme bot works on this sub. https://play.google.com/store/apps/details?id=com.keramidas.TitaniumBackup here's the link.
Well for me the 9.31.1.0 is working perfectly fine. You can grab the apk from here, install the downgrade and get the latest normal Snapprefs version from the Xposed installer of you want to get to the level I'm at. As I have no clue how the jenkins builds are working I don't know of there is a working way to get a newer snapchat version running thou
EDIT: I just got the 9.35.5.0 just to test it. It does not work in combination with normal 2.0.0 beta. Maybe someone can give me some info on how to get a jenkins build running so I can test that as well?
EDIT 2: Now I've tested the latest jenkins build (or at least the one I found on the site, it's quite confusing) in combination with the 9.35.5.0 and it doesn't really work either. So I'm back to the 2.0.0 beta with 9.31.1.0, it works fine.
