Strange. I’ve updated to latest and this issue persists..

I’m pretty confused, because it seems like I can add even non-existing users and (x) is displayed next to their name.. So usernames are not corrected automatically when inserting into PM?

I think that adding information about which user was not found into error message would be very helpful.

My use case is inserting 50 members by copy-paste and there are evidently some letters not written in proper case. The only solution for me is to invite them into message one by one.
