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.
