The body of the Email does not respect format

Hello community, I have a question, I have a workflow that sends an email based on a Google Docs template, I have not made changes to it.

A month ago the body of the email was displayed like this:


Now it looks like this:


As if the format (bold and color) were not respected

Does it only happen to me? And if so, any suggestions?

Just because of new PDF engine, better to report to
CSS (for styling) is ignored or not respected to convert.
