I just opened the chocolate bar for the first time after purchasing it from the store.it has a white powdery substance on it. Im worried it is mold . I checked the expiry date, it says BB 03/07/31. Im not sure what the other codes are but it says P 05/12/20. I haven't done anything to the chocolate before opening it, and I haven't tried eating it after opening it . Can someone please explain what is wrong with this lunchbar. Im super sad I have my period and was really looking forward to this.
