HabPanel Persistence across devices?

I am having trouble getting HabPanel persistence working, I have looked at the documentation and can’t work it out. Whenever I change the weather widget it is not updating on the other computers only the local computer? The setting for panelsRegistry is empty. How do I set up HabPanel to be persistent across devices?

I must have missed something somewhere?

OK, so I did this step wrong, after hours of reading and searching. I feel stupid now. I read this document so many times, I saved and saved the panel, just not to a new panel.

click on the Save the current configuration to a new panel configuration link
