Welcome to the forums @Pratheeba!
I presume you are attempting to log food through your mobile device? In this case, please log out of the Fitbit app and restart your phone. Once you've done this, let's check if there's a never version of the Fitbit App for iOS.
Let me know if you have any questions, good luck!
