Just now, as a test, I sent a post titled “BlueMail - test” using the BlueMail 1.9.48 email client (phone: Xiaomi Redmi 8, OS: Android 10):
The standard font is set in the email client, I haven’t changed anything here. The post consists of three paragraphs of “Lorem ipsum…”: the first in bold, the second in regular font, the third in italics.
The problem is that not only the content of the post, but also its title and date are written in a completely different font than the one written in my CSS. Why?
