OK. I created a 4 page file using spreads with InDesign. The spread feature in InDesign hasn't changed at all in the last decade if not much longer. The first page is a “right page” (i.e. the right page of a single page spread), the second and third pages comprise a full two page spread, and the fourth page is “left” page (i.e., the left page of a single page spread). I exported PDF using the Spreads option. Both the InDesign document and the resultant PDF file are attached for your perusal.
Opening the PDF file in Acrobat DC Pro, there are three physical pages. The first is an 8.5"x11" single page spread of page 1. The second is a 17"x11" double page spread of pages 2 and 3. And the third is an 8.5"x11" single page spread of page 4. This is exactly how one would expect the PDF to be when this InDesign document was prepared as it was and exported with the Spreads option.
I then copied the PDF file to my iPad running the latest version of the Adobe Acrobat Mobile Reader. I certainly did get the exact same results on the iPad as I got on my by honk'ing desktop system running WIndows 10 and Acrobat DC Pro.
Note that to both PDF and Acrobat, there is no such thing as a “spread” versus single pages. Spreads are simply physical pages consisting of multiple (typically 2 but possibly more or one) logical pages output as single pages. Thus, no version of any PDF reader can distinguish between logical single pages and spreads of multiple logical pages.
Then how do we explain what you are reporting? My best guess is that although your InDesign document is setup as spreads, you inadvertently exported as single pages (the default option) and had your copy of Reader or Acrobat set to show 2-up pages (“two page view”) upon file open. Since the Adobe Acrobat Mobile Reader has no such “two page view” option, you only saw single pages since that was exactly how the PDF was exported from InDesign.
