Steps to reproduce the issue:

On a Maui Blazor project, have an expired access token
Call the api with expired access token
Api returns an exception with Unauthorized

We noticed a difference between our Blazor and Maui Blazor versions of the app. On Blazor, when the access token is expired, the application attempts to refresh the token before sending a request to the api. Therefore, the api doesn't return an exception and everything is fine.

On the other hand, in Maui Blazor, the app doesn't seem to refresh the expired token before sending a request. Thus, the api returns an unauthorized exception and our application shows us the reload button.

We also noticed that in our Blazor project, there isn't any refresh token and the login flow seems to be triggered instead (without asking the user to reenter credentials). In Maui Blazor, we do have a refresh token. Heres a screenshot of the http requests for the blazor project:
