Responsive and mobile format

Update - I'm updating this to a bug report - when I use the responsive styles it's not even rendering the responsive styles in the step 4 preview, nor are they making it into the email that gets sent. Maybe I'm doing something wrong, but still hoping to hear from others that ARE getting this right. Thanks all!

Is anyone out there trying to do the lords work getting this gutenberg responsive function working for email? I have spent tons of time trying to convince the mobile responsive styles to load at all and am simply not seeing it in my testing. Changes that I see in the campaign editor aren't making it to the client - even simple things like mobile color change for a heading or something.

I understand that NOT styling is the best styling for email, but you try and tell an ecommerce client who came over from mailchimp or klaviyo that they can't reliably style their mobile template.

Anyone working on high-touch email template design - would love to form a working group or something to really dial in both a) deliverability and b) formatting.

Again, yes, I understand that those two are separate concerns, but i suspect many of us are dealing with both issues to some degree.
