Snapchat setting won't stay? (s6)

[AC Question]

I want to enable the vibrate and sound option but it's stuck on the original setting (wake screen and blink LED.) Even if I deselect the other options it just goes back. (I don't see any button to save the settings just the back option and that's it :c)

I have the Galaxy s6 and it's new so I don't think the phone is really a problem, just the app. Thank you for your help.

Having the exact same problem. Emailed them and contacted on Twitter, but no response just yet.
I have tried reboot, reinstall and even signed up for the Beta. Nothing worked.
