Why In prototype preview some sections not shown

Why In the prototype preview some sections not shown?

Hi there,

Thank you for your post! I’m interested in knowing more about the sections that aren’t visible to you. Could you please check if the layers that aren’t showing up are actually frames?

If the issue continues, would you mind sharing the file with some additional details, such as which specific frames are not appearing? This information would greatly assist us in troubleshooting the problem.
