Need help, please! Why is it that every time I view my page in Notion through the web browser, I get the message "Page not found. Either this page doesn't exist or you don't have permission to access it." Then, there's the option: "Back to my content," but clicking it does nothing. I'm definitely logged in with the right account/email address because the desktop works without issue for me.
Being logged in using the app is not the same as being logged in in the browser, so it does not matter that you see it in the app, you must login using the browser to see it.
If you want it to be public to anyone, you must enable that in the sharing options at the top right, otherwise only you will see it.
