Blazor Delay in AccessToken being ready and authorized view showing

[jbomhold3]

Describe the bug

When making an HTTP call inside a component in the component the access token is not ready for a short time after login even when the authorized content renders. The call throws a exception however oddly enough the request still has a token attached.

blazor.webassembly.js:1 crit: Microsoft.AspNetCore.Components.WebAssembly.Rendering.WebAssemblyRenderer[100]
      Unhandled exception rendering component: ''
Microsoft.AspNetCore.Components.WebAssembly.Authentication.AccessTokenNotAvailableException: ''

Having the same issue in the GA version. Have only seen it happen on an iOS device, however.

Same issue here, when you try to send authenticated request in the GA version in component after-render. Token is not available despite the successful authentication

Hi @javiercn , is there any update on this Issue? I am still seeing this on Blazor WASM 3.2.1
