plex server setup on Synology

[Enquiries]

hi, I was watching/learning your YT video (https://www.youtube.com/watch?v=XUXJFu1LtJ4), and I have questions:

1. what if my Plex Server looks nothing like yours after the first five minutes? how do I reset?
2. I noticed while in Plex interface, you are logged in to an account...that's not covered...

Thanks for your time!

Nick
