    Yeah, some quick Googling makes it seem like that there is a combination of iOS native PDF viewer being buggy along with handling color models, specifically, color models for print. Though this does seem to be a historical issue as old threads about color models out there dating back years.

    In this case, can understand as this is probably the physical brochure one gets at the dealer.

    Not seeing any viable built-in workaround on iOS. Dropbox and Adobe Reader apps render the document fine. MacOS as well. If one prints/exports the PDF as a PDF from MacOS and put on Dropbox, iOS Books reads the document fine (but is huge).

    There is a Shortcut in the gallery that allows for downloading of a file to cloud storage. Get it and invoke via Share Sheet, then export/open-in Adobe, Dropbox, etc.

    (Deleted Shortcut: there is a good one in the Shortcut Gallery)

    I have this exact same problem in iOS 12.1 and macOS 10.14.1 Elements of PDF magazines don't display properly. (see attached image)

    This problem has been around from a long time as @NoBoMac says. It’s a fault in the default iOS PDF browser but Acrobat’s own viewer works correctly. Here is the same page of exactly the same file rendered by GoodReader and by Acrobat side by side:

    How crazy. I’m surprised it’s not bigger news. The magazine I’m having issues with now worked as recently as 3 or 4 months ago. So I wonder if it’s become worse with the last round of updates.

    IOS 12.0.x was working fine. This bug was (re?)introduced with 12.1 and is still present in 12.1.1 beta.

    That sucks it’s still in the 1.1 beta. It means a fix won’t be till next year at the earliest.

    I’ve filled in the bug report online for both Mac and iOS. But you have to figure they know about it already.

    Sounds like their regression testing needs a boost...

    I didn’t think to send an online link when I bug reported to Apple. I’m sure they must know?

    Does anyone know if it’s fixed in the latest beta?
