Link in bio issues

I just completed my first app and it’s been a learning experience but fun. I create a link-in-bio styled page but I’m having a couple of issues. I want people to be able to visit my page and see my profile picture, links, etc.

Issue1: When I logout and visit my picture disappears
Issue 2: I need the action button to disappear if the user isn’t logged in. Can anyone help with this?
