Hi @juanajaafar,
They are both correct, but allow me to explain what’s the issue
If you’re planning to just divide a text content then please use standard Wordpress editor, but if you wish to use the builder then don’t divide the text content, but the sections.
What I’m saying is, don’t just place multiple <!--nextpage-->
on same text content, in the same section if you plan using it in the builder. Example
[section]
[text]hello worlds[text]
[section]
[section]
[text]hello worlds <!--nextpage-->[text]
[section]
[section]
[text]hello worlds <!--nextpage-->[text]
[section]
The purpose of <!--nextpage-->
in the builder is not just to split content, but to correctly split sections from each other. Else, the layout will break especially the shortcode, that’s why you’re getting a shortcode at the end since it’s not properly divided. Example,
page 1
[section]
[text]hello worlds
page 2
[text]
[section]
The TOC is just a shortcode that allows navigation linked to pagination but it’s not a requirement. You can add pagination without it. But make sure to implement <!--nextpage-->
properly in the builder. The layout could also have hidden sections meant for other devices, so please properly decide where and when to use <!--nextpage-->
within the builder.
Thanks!
