You can adjust reward rates in the "Card Settings." Go to the Wallet tab, then tap any card to open "Card Details" and then tap the gear icon on the top right.
You can also access "Card Settings" for connected cards by going to Accounts and Cards (top left icon on Wallet tab) and tapping on the gear icon next to a card.
Reward Program
You can change the reward program associated with a card. For example, maybe a card earns Membership Rewards instead of Cash.
Reward Group
All rewards are organized into reward groups. Reward groups have:
The same reward rate (e.g. 5x)
The same start & end date
The same limits
The same restrictions
You can modify existing reward groups, delete groups and create new groups altogether.
Reward Group Customizations
Name: Customize the name so it's easier for you to understand.
Icon: Change the icon that's displayed in Card Details.
Included Categories: Categories where you'll earn bonus rates.
Excluded Categories: Subcategories where you're excluded from earning bonus rates. For example, you may earn 6% on groceries, but Walmart is excluded.
Reward Rate: The bonus you earn. Note that the reward rate will be multiplied by the point valuation and the reward multiplier.
