A client of mine was requesting having the email render properly on the blackberry OS 7. I checked this article
https://www.campaignmonitor.com/dev-resources/guides/mobile/

BlackBerry OS 6+ support responsiveness
But it seems the client was just getting the desktop version instead and media queries werent working

I have tested the email and looks great on all the responsive mobiles like samsung and iphone but this is what the client is seeing on his device.

Only thing that worked I realised what when I set my container width to 100% then it got into fitted into the device but it also rendered awful in outlook.

So I am just checking if anyone faced any issue like this?

Thanks
