Hi @Michel, Hugo , The delay in updating the redirect URL in your Azure B2C tenant could be due to the time it takes for the changes to propagate throughout the system. This is a normal process and can take up to 45-60 minutes. If it takes longer than an hour something could be misconfigured, but I wouldn't worry currently. Changing the redirect URL isn't something done too often so it shouldn't be an issue. Please let me know if you have any questions!
