When launching Soda via Facebook, it brings me back to the first page. It seems to be a cookie or something on my MAC, since my daughter logged into her Facebook account on my computer and it does the same thing. Works fine on my tablet.
Just to add, I'm not loosing my progression, the game just loads to the first screen and I have to scroll though multiple stages to get back to my progression
it seems to be associated with the language. if I load via a french Facebook / preferences, the issues shows up. If I switch my Facebook to English, it seems to load fine.
