How do I scale UI?

This is really confusing me, I have looked at tutorials forever to no avail.
How in the world do I scale UI perfectly for all devices? No video is working.

Can a UI designer help me out here? I genuinely have been trying to figure this
out for months.

Use the “Scale” rather than the “Offset” property.

This does not work.This has came up in multiple tutorials.

It’s literally how you do it, you must be doing it wrong if it doesn’t work. Can you show an example of what it looks like when you use Scale vs. Offset?
