I have created my account with Duplicati and have installed the software. I also have an account with Backblaze B2 along with the Key ID & App ID. But there is no way for me to create that first backup. I would go to the old UI but there is no way to do that. How do I get the software to allow me to set up my first backup?

Oh. You’re not even browsing to your local Duplicati (generally at URL localhost:8200).

I launched the Duplicati software again and it launched to the old UI so I’m in the process of getting this set up…I hope. Thanks
Monitoring with Duplicati Console is saying that’s for monitoring.
Looking at the screens at app.duplicati.com looks the same.
Duplicati Documentation has GETTING STARTED pages at top.
So on that one, you can switch with “Use new UI” on bottom bar,

EDIT 1:
The Duplicati Console directions should clarify using the local UI.
EDIT 2:
I’m also just following docs I could find. I’m not discussing Agent:
The Agent requires an Enterprise plan
so presumably does more, but I don’t think I’ve seen latest details.
