I think it’s very unclear what this error message wants me to do.
It happens for example if I try to comment on a post from kbin.social when I’m logged in to lemmy.world.
Where in “lemmy” am I supposed to update my settings?
I’ve set any language setting I can on my kbin.social profile, lemmy.world profile, and in the Voyager app.
Are you using an app? I noticed that a lot of apps don’t have the language dropdown which is problematic. You sometimes need to resubmit your comment while selecting English. Lemmy is a web native app and you can install it on your home screen as an app. I found it better than faffing with apps out for the moment due to the state of early development.
You can see the language box below my comment. :)
