Just finished building our splash page, and while the desktop version looks great, the background on the mobile version (iPhone 6, both Chrome and Safari) of the page is very grainy. The image is very large and high res, so I don’t know what the issue is.
Can you share a screenshot? I just tried on my iPhone 6 and Chrome and it looks quite good to me. We do optimize image sizes for mobile for faster loading, so maybe we’re being too aggressive there, but show us first what you see.
