Beside the obvious don't reddit, it happens alot in the kbin (web app) and lemmy apps too.
I've taken to stopping to randomly copy my comments to the clipboard, or if it's an extra long response, writing it in a different app and then copy pasting it.
I was gonna say... With Lemmy it's more likely that it'll just fail to post comment, but I'm willing to deal with that as the fediverse grows. Devs are working hard to smooth things out so I'm ok with a bit of jank here. Fuck reddit though.
I’ve had this happen on kbin quite a few times as well, but even if it redirects to a new page with an error message, it always saves the text in the input field. Haven’t lost a single letter once.
Does it work differently for you? At what point does it lose some of your content?
Not to rub it in, but here’s my response using the memmy app. (To be fair, I’ve read the development version has been a little crashy of late, but the app store version has been stable af so far in my experience.)
