double error message

[aj-codecov]

Describe the bug
Duplicating error messages:

To Reproduce
I got rate limited with an error message > kicked out to the login screen > logged back in > rate limited still with a double error message

Expected behavior
One error message screen

Additional context
Per Nick:
This error is arising because we have two network error boundaries that both display this logo, the optimal solution would most likely be to remove the logo and content/create a custom network error boundary component for the top components (global top banners & header) that doesn't display anything.
