Hi, thanks so much for your great tutorial, finally I can log in my project with a real API server, but I don't know how to use JWT authentication in other pages(still 401 Unauthorized), I noticed in /src/app/home/home.component.ts, you imported AuthenticationService, but you didn't use it only use UserService. Could you please help me figure it out? Thank you so much for any advice!🌹☕️
