Initial value vs. preview value?

Should this be the same? Whenever the app was updated, Set Preview Value was introduced and now it differs from Initial Value.

I did confirm though that these values are different.

Hi there!

Initial value is a starting value given to a variable. Say you have a page variable “titleText” and you give it an initial value of “Hello world!”, then that is the value the variable will have when the app is started.

Preview value is a value that will be displayed in the app builder. This is so that even when the app is not running, you can still specify some content to be displayed in the app builder view.
If you leave the preview value blank, then the name of the variable will be shown in the app builder (e.g. pageVars.titleText). The preview value has no effect on your final app.

Hope this clarified it a bit!
