Samsung Mail does not show BACKGROUND image
I'm working on a way to use background images to enhance design possibilities.
I've come to a nice solution using bulletproof backgrounds, but I'm having trouble with Samsung, which I though supported them.
The background just disappears and I don't know why. Any ideas?
Here is the code: https://litmus.com/builder/e50e714
I also find problems with Windows 10 and Gmail IMAP in litmus (testing real devices works perfectly in Gmail IMAP) but I guess there's nothing to do with Windows 10, is it?
Thannks a lot!
