I have tried over a half-dozen solutions suggested on Stack Overflow, and the only thing that worked for me was this:

<div class="row" style="display: flex; flex-wrap: wrap">
    <div class="col-md-6">
        Column A
    </div>
    <div class="col-md-6">
        Column B
    </div>
</div>

I got the solution from https://codepen.io/ondrejsvestka/pen/gWPpPo

Note that it seems to affect the column margins. I had to apply adjustments to those.
