Assistance Needed: Universal Login Logo Upload and Custom Text Update

Universal Login Logo Upload : I am currently facing difficulty in uploading the logo for Universal Login. Could you please guide me on how to upload a logo without the link?

Custom Text Update : I recently made some changes to the custom text under the Universal Login section in Auth0 dashboard. However, these changes do not seem to be reflected on website. Could you please advise on how to ensure that the updated custom text appears correctly on website?
