Love the new app

The new app is great. Love the new look. The tiles make it easy to keep my different accounts together. Keep up the good work!

Calendar design for bill pay is (still) terrible.

The calendar design for bill pay is terrible as it does not reflect the design of an actual calendar. Is merely a scroll wheel.

Also, any notices they display on the splash screen are virtually unreadable if you have auto-login enabled. Have to block Face-ID with my hand just to read any notices because I have yet to find them elsewhere in the app.
