to really help you out, could you share the relevant parts of your App.razor file and the _Host.cshtml file? I need to take a look at those to see if your Microsoft Identity settings are set up correctly. That way, I can better understand why the sign-in redirect isn’t working, and whether there’s a missing middleware or something else going on. Right now, I can only give general advice — but if I can see those files, I’ll be able to give you a more accurate solution.
