Has anyone else noticed that about 50% of emails (HTML, usually responsive) have started to render slightly off-center in Apple Mail (iPhone) for iOS 10? I design and develop emails and ever since updating to iOS 10 my emails are rendering with with extra space on the right side than the left on my iPhone. I have noticed a similar issue from emails from major brands such as Geico, Calvin Klein, and Uniqlo.

Just curious if anyone has noticed and if this is the result of a change that us email designers/developers will have to find a fix for or if it is just a bug in the newly updated software!
