Hi 👋 Kathy-Lawson-Navy-Butterfly
Great news you also want to open a personal account at bunq. 🌈
My guess is that this is because you either use the same email address or the same phone number as your business account. I suggest signing up your new personal account with another phone number and email address, so they don't try to overule each other. It's indeed necessary to open a completely new account if you want it for personal use. If you would open an extra monetary account within your business account it would be on the businesses legal name.
If you need some private help you could contact support under profile and then 'Private Matters'.
Let me know if you have any further questions.
