Gmail App (android) responsiveness preview



I’m testing an email of mine via the “Test in different email clients” feature. The CSS Media queries seem to not be respected on the Gmail App (android) preview. I read that gmail used to not support media queries but recently they started supporting them. So I was wondering if maybe that preview is running an older version of the app? Is there anyway to confirm what version of the app is running on that preview?

The Gmail App – IMAP preview does look correct, though. Do you know the difference between IMAP and the regular one?

Thank you!
