Additional information

When user proceed steps 1-5 and then refresh page, then he will redirected on Home page with notification You need to be logged in to see this page (but user still stayed logged)

Reload of any "My account" section page (as authenticated user) redirects to home with this notification. I think it's related to SSR "My account" pages reload logic for unauthenticated user.

We've introduced it a while ago to redirect unauthenticated users from "My account" to "Homepage" on reload.

Maybe we should not redirect user at all in this scenario because we can't detect if user is authenticated on SSR
