Page Builder – Cannot view content in iPhone Reader mode

從屬相看透你的一生！越看越准！（上）鼠牛虎兔

I have just built an article with page builder, everything looks great except that it cannot be viewed in iPhone “Reader” mode (the top left button with 3 long line and 1 short line). I think it’s an issue with the page editor, anyone experience the same?

Thank you all for your great support!
