Hello,
I am using a iPhone 6s with the latest updates for all software.
A few weeks ago my Mail app stopped receiving pdf files properly. They would not open.
Then just as suddenly it resolved itself, showing single page PDFs, like it would a picture file; but not multipage PDFs, it will just show the cover page. It won't let me open in iBooks (or any other app) either.
Please help, I have no idea what triggered this as it was never a problem before.
Thank you.
