Far Top left of your screen you should see a little trophy in a button it should be darker than the other 2 icon next to it. Will have a little glimmer to it like it is trying to catch your attention .

That is the icon for Feasts of Valor. Open it up and look for crowns at the top of the tabs. Follow the crowns. Rewards that are not claimed will have a explanation point next to them.
