Hi! I bought one flavored yogurt earlier. At first, it tasted sweet, which I assumed was because it contains monk fruit, as it mentioned. However, after a few minutes, it started to develop a noticeably sour taste. Is this normal for a flavoured yogurt, or could there be something wrong with it? I'm a bit concerned because the change in taste was quite sudden, and I'd appreciate your clarification. Thank you!
