No way to fix your account name if it was misspelled in the app but it can be done on the website. "Contact Carta Support" link opens email client with a blank "to" field so can't get help using it. Support phone number can be found when you select "customer support pin" which is not intuitive. Called support and it was a short wait and they were very helpful. The app allows you to simulate exercising your options which helps a lot with understanding how options work.

Update Oct 3, 2025: Still logs me out after opening the app after a month or two. :( Old ---- Logs out every time I open the app.

Terrible experience with Carta. I exercised two orders and wired funds internationally. I was never informed the funds were insufficient—no warnings or reminders. I only found out when my company canceled one order. I reached out right away but didn’t hear back for a month. When I finally got through, it was too late. Awful communication and zero accountability.
