Thanks for sharing your feedback with us, @Brie_Chapa! As it stands, it’s not possible to upgrade specific users to Business when you have a Premium plan. There are some workarounds if you change your plan to a Division, I recommend you checking this thread: What I learned about divisions 😅
In the meantime, I’m merging this thread with the main request to consolidate votes and feedback. We will post updates as soon as we have any!
