Hi there @glombek!

Firstly, a big thank you for raising this issue. Every piece of feedback we receive helps us to make Umbraco better.

We really appreciate your patience while we wait for our team to have a look at this but we wanted to let you know that we see this and share with you the plan for what comes next.

We'll assess whether this issue relates to something that has already been fixed in a later version of the release that it has been raised for.
If it's a bug, is it related to a release that we are actively supporting or is it related to a release that's in the end-of-life or security-only phase?
We'll replicate the issue to ensure that the problem is as described.
We'll decide whether the behavior is an issue or if the behavior is intended.

We wish we could work with everyone directly and assess your issue immediately but we're in the fortunate position of having lots of contributions to work with and only a few humans who are able to do it. We are making progress though and in the meantime, we will keep you in the loop and let you know when we have any questions.

Thanks, from your friendly Umbraco GitHub bot :robot: :slightly_smiling_face:

Hey Joe, this is expected behavior as the blue page you see is the callback page for the oath flow. Which then redirects you to the client

Hi @glombek, I'm following up on this; as @Migaroez said, the OAuth flow has a landing page, which is shown only briefly if you have a fast connection or are on localhost, etc. I'm wondering if we really need this landing page in case of a normal login, but we had some issues with capturing the return code to exchange for a token, so what happens on the landing page is roughly

Get the ?code parameter from the URL
Call the token endpoint to get an access_token
Store that in local storage and memory
Redirect to the backoffice app

Do you feel like having some other kind of loading screen would help as this process transpires in the background? Maybe a loader bar/circle instead?

glombek commented 2 weeks ago

Hi folks, thanks for the replies. I appreciate this is as designed but my issue is more that it feels incomplete than its actually a technical problem. A loading screen would be the nicest experience, but even a if the landing page wasn't dark blue in contrast to the two white pages before and after, it'd be less jarring!

JasonElkin commented 2 weeks ago

I've noticed this too and yes, a loader instead while the redirects happen would be better.

As far as the user is concerned, logging in is a single operation - they don't need to see these steps.

Hi all, I hope that #17618 will improve this experience.
