If you navigate off the page by accident it doesn’t always ask an “are you sure?” to protect your work.
This is a problem on other forums + SM, e.g reddit, but seems prevalent on lemmy.
That’s all I’ve got to say. If there’s eventually some solution or improvement to this it would be nice.
Might just be a problem with how i use my mobile device;
on this occasion i opened up anki by highlighting part of my text and then found the browser closed, so perhaps i should have just backspaced from anki to navigate back to my in-progress commment. It has happened on other occasions as well - i think one common thread is that replies to a post stsy saved but replies to a comment/reply are collapsed upon accidentally minimising a browser, and you lose it all.

Yeah, it might be whatever frontend dbzer0 uses. Also, Firefox (latest) and macOS (26.4.1).
DB0 seems to use the normal lemmy-ui without any changes. Though I dont have an account there to test it. Best if you contact the admins on db0 to ask about this.
