Templates now flag the problem before Meta does
The template builder catches limit and variable problems while you write, and previews formatting the way WhatsApp will actually render it.

The template builder now surfaces the things that cause rejections while you are still writing.
A rejection costs a day or more. Most of them are mechanical: a body over the character limit, a variable with no sample value, formatting that WhatsApp renders differently from the editor.
- Character limits per field, counted as you type
- Variables that have no sample value attached
- Formatting rendered the way WhatsApp renders it, not the way the editor does
- The essential details gathered onto one review screen before you submit
