No, this is not about how to feed my pet, it's that i'm unable to. Ever since I leveled up my pet once and had gone to the skills tab, I can't find a way to get back to the feeding tab. I've restarted the game, waited till the next day to see if anything changed, and tried just dragging the food to the battle sprite window. Nothing seems to work.

Sorry if this has been asked and answered already!
