Default [Q] Snapchat and Cyanogenmod 11

Does anyone know of an issue with Snapchat and Cyanogenmod 11? I've recently flashed for the first time, I'm happily using cm11, but Snapchat hardly works at all. I've tried the alternative "Snapsave". But with both apps it might work once or twice, but then either doesn't receive snaps at all, or it does, but I can't access them. And sending fails. I've tried several times uninstalling and reinstalling, I even started a new Snapchat account. But whatever I do I'd say I have a 10% success rate at best. Are there any known cm v sc issues, or can anyone suggest anything? Thanks.
