lost document saved in iCloud drive

I was making a document with Pages in iPad Pro and it was saved in iCloud Drive. I had to replace it with MacBook Pro (as I was not very much happy with iPad Pro as a replacement for my old MacBook) and once I opened the document through pages in my MacBook Pro... the file is there but only the first 2 pages. I had written almost 26 pages.

is there any way to retrieve it ?
