Joined recently and looking for advice!

Hello everyone! I (24F) joined Wealthfront about a week ago and I have opened up a regular Cash account and I’m already loving it so far, and my boyfriend might join along with me (so we can get that extra .05% APY boost!!)! Do you guys have any advice or tips for beginners using the app? In regards to everything, the other accounts that can be made, investment, %’s from check to put in (after expenses are taken care of of course), all of it! Thank you all so much in advance! 😊
