Nextpage not working on preview

I’m writing a 2 page post (or more), I include the right <!–nextpage–> code, when I click to preview the post everything appears normal.

the page address:

?p=58048&preview=true

But when I click to go to page to, nothing change, it shows page 1, always, I try to go to page 2/3/4/5 and always show page 1, no change.

page 2 code:

?p=58048?page=2

I already tried including the ‘preview=true’, but no luck.

Can anyone check it? Is it only me?

Thanks.
