Nova automatically understands when you're transferring money across accounts that are connected. However:
The best way to correct this is to create offline account(s).
<aside>
💡 Always mark your transfers to/from offline accounts as Sent to/from offline an account
This way, Nova will understand that your transfers out aren't expenses, and that your transfers in aren't income.

You're done! Nova will automatically update the balance of your offline accounts by creating an offline transaction 🥳.
