When I try to use the guild chat as my main (Peregrine), it only gives me options to chat as my alt (Osprey) who was the my first character to join a guild. I have logged off and on and switched between my 5 alts. All can only use guild chat as Osprey in the channels Osprey has access to.

TY Simoyd I didn’t see that.
Also, my main is in a guild that none of my alts are in. I can’t message that one either, so it extends a little further than what that post suggests.
