Ok. I found the fix. You have to add the google fonts import/link WITHIN the paragraph text box e.g.
<link href="https://fonts.googleapis.com/css?family=Open+Sans:300,300i,400,400i,600,600i,700,700i,800,800i&display=swap" rel="stylesheet">
and then from there, you can add inline css to your text. After this, I was able to utilize the <strong></strong> tags to get the heavier font weights, but you can also indicate the custom weight that you imported. Clunky but I really need it done now. Hopefully this is at least helpful to somebody… and hope this can be addressed in the next update!
