On desktop mj-column is stacked in thunderbird and other webmail based clients

[webthingz]

Hi All,

I have a template with a 3 column section. This working fine on mobile, roundcube, gmail and outlook. But it is not working on thunderbird en my own webmail client from Axigen. I tried with mj-group and then the columns are good on de desktop but the columns need to be stacked on mobile. Breaking my head on this..

Greetings! Ziggy
