Has anyone had trouble with email rendering on iPhone 6 and Droid? Our test emails arrive with images in places that they do not belong (a sliced graphic from the bottom of the email swapping in for a slice at the top, for example). All image paths are correct. When we clear the cache on iPhone 6 and Droid, the email then renders as it should.

Is it possible native mobile email apps just can't handle multiple vertical slices at the bottom of an email? I know they used to work just fine.

Thanks for any help!
