I hope this is the right tech support comm for general Lemmy issues; not sure if this is limited to just Lemmy.World nor do I know if my problem is instance related…

Anyway… Got a DM from a user about an hour ago, but when I try to reply I am given an error that the user does not exist. Their profile is viewable. They just messaged me. I know they are active on the site, as I see them posting pretty regularly… Not sure why I can’t DM them back tho.
