I’ve got a report of the same issue with white text on white background..
when the user tries to type a reply on his iPhone, the white text on light gray bg makes it almost impossible to read (see the “Hi there” text below..)
it appears to be a combination of the default dark mode styling within the Discourse email template and how the iPhone handles (or mishandles) that styling. Is there a setting the user can switch to change this? Or maybe a quick and easy CSS fix I can add to an email template?
Thanks
