To fix connection errors:
- Go to the "Move money" tab (🔃).
- Tap "Linked accounts."
- Look for a red exclamation point next to an account (this would indicate a connection error).
- Tap the institution with the error, and select "Update credentials" to enter your updated information.
If this doesn't resolve your issue, let us know by going to the profile tab (👤), tapping "Help" then "Contact support."
