Responsive Email on Native App Android 4.4.2
I've build an email that works fine for most of the email clients (with desktop fix for Gmail App),. I can see it properly on the native Android App (Android version: 5.1.1), but one of my clients is having trouble with it.

Any ideas why this is happening? Can it be due to an old version of the app?
Any help will be appreciated! Thank you so much!
