@User Been a while since this message, but have you had issues with CORS with 9.1.2 as it seems to break cors via

u.RunPostPipeline();

whilst sticking with

RegisterDefaultRequiredMiddleware

? as means it can't be injected between

useRouting

and

useAuthentication

?? 😦 https://discord.com/channels/869656431308189746/882984410432012360/918907913429454930
