Question

Figma

The present preview shows only one screen with the project page. Previously, it was possible to switch between pages from below under the iPhone. Now there are only 1/1 even though there are many pages in the project. Where to poke how to set up?

Answer 1

I understood everything! As soon as I added prototyping it happened. And I added it only in one place. Now I connected all the screens in prototyping and each window was displayed. Wrongly explained but everything works)
