Same here with 4 in a row, was broke by last update. Also, the race just disappeared too. Regular Candy Crush had issues from the most recent update, but it appears to be fixed after my most recent launch of it. Not so with Soda. Still messed up.
A few WEEKS? It's not worth playing this game if you're not competing in four in a row. By the way, this has happened to me now too. I completed and won a game, got my prize, it asked me if I wanted a new board and then brings me to the home screen.
Some players have lost the 4 in a Row, as mentioned here, and for some other players, 4 in a Row is not working properly. You can find that thread π here
