There is a know issue with miss matched css prefixes when images are turned off by default.
Initially on load the CSS will match then when images are turned on the HTML refreshed and creates new unique prefixes but the CSS stays the same so they no longer match.
So looks like you're using shoppify, you could try and fix the image widths with that.
I'm not tried that with shoppify before but works with other cdn's I've used, found a couple of articles that might help.
AOL is now using Yahoo rendering which includes putting images in the yahoo image proxy
https://ecp.yusercontent.com/ so I'd guess LItmus would now track them both the same.
Also I'd guess they are no longer blocking images by default which could account for such a large jump. Or it could be an issue with tracking via the yahoo image proxy
If you add a margin to the
<ul> then it'll break in Mso Outlook. To get around this just add a div around the outside and put your margin on there.
Ha actually it looks like it's supporting the old
:checked styles from a couple of years ago.
So feeling more confident it's only a temporary thing.
We're seeing the same thing too. My guess is some code was pushed accidentally and this wasn't intentional.
Hopefully they'll roll back the change or make the full move over to New Gmail quickly.
