Using Pages 13.0 on macOS Monterey.
I have a Pages document where I have paragraph titles formatted as style "Heading", and the remaing part as style "Body".
I wanted to insert numbering into the Heading. I proceeded as follows:
- Put the cursor on the first paragraph with format "Heading".
- Change in the "Format pane" (where "Heading" is selected) "Bullets & Lists" to "Numbered"
- Click the checkmark for "Tiered Numbers"
- Select the radio button for "Continue from previous"
This made my first heading indeed be prefixed by the number 1, but the second heading further down still does not have a number. Checking the Format pane, I placed the cursor into that second "Heading" paragraph and found that my changes have not been applied. I did the same to that paragraph and now got the number 2 in front of the heading.
Of course I don't want to do the same process over and over again. The style should be changed uniformly to my whole document. I found this discussion which suggests that an "Update" button is supposed to appear next to a style name, when I change the style, and that this button would make the changes permanent. However, I don't see such a button.
