Adobe Acrobat reader doesn't save the file view options. So if you rotated the file in reader, then it'll not save the PDF file. Because reader is not supposed to make changes to the PDF File. If you want to edit the PDF file for such changes, you need to download one of the apps -
One of the app from above will allow you to edit any PDF that you open with it. And once opened you can rotate the direction of the images inside the PDF or the PDF files pages can be rotated as well. The above apps are not free, so you have to purchase them to make such changes. Or you can get this done from freelancers on upwork or fiverr.
You can also do this online from some of the websites which allow editing. However not all of them offer the view rotation option available for free.
