Question: Why can I not open a pdf attachment in Mail on my iPhone X?
I just bought an iPhone x at Best Buy with a device agreement with Verizon. Best Buy sent me an email with my device agreement attached as a pdf. If I open it on my iPhone X, it has an attachment symbol to the left of the preview, and when you open it, there is no attachment. It is a Gmail account. If I go to gmail in a browser, or the gmail app, there is definitely a pdf copy of my device agreement attached and opens fine in both.
iPhone X, iOS 11.2.1
