Hi. Newbie here. Starting today protein isn’t adding to my wheel . Thoughts ?

It's bound to be a settings problem but hard to say what without your device in hand.  I initially had my friends' set to diabetes carbs and grew frustrated with the way it showed her info, so I switched her to the regular setting, it made it a lot easier for me to show her how to use the app.  I suggest you go to settings and your account and look around for the culprit.
