Links to pages within PDF document don't work on browser version of Acrobat Reader

Hello, I have a large PDF that has many links in it that link to other pages within the document. For example, it has a table of contents with links to the various pages throughout and a home button on each page to take you back to the table of contents page. The links work perfectly in the desktop version of Acrobat Reader. I added a link to the document on our website, but when you open it from the website it opens the PDF in the browser version of Acrobat Reader and the links go to the wrong pages. The links still take you to a different page, but it takes you to one page off of where it is supposed to go. Why is this happening?
