Hello, quite same bug with myself: last time You made new chat working for everyone, a month a go or so, everything was fine. Actually, after I pm anyone, all of the further nicks I pm do not show anymore in the upper bar, it just remains the first one I pm'd and, trying to delete it, it doesn't work and that conversation remains in the upper bar, until I logoff. If any user replies to my pm anyway, I just know it by an alert on the upper gray frame of browser panel and, to read it, I have to "send a message" to such user, scrolling from the list. Definitely not that easy to use this new chat, this way. (Accessing with Mac OS High Sierra 10.13.6 and Safari 13.1.2). Thanks in advance for attention.
