When chatting with multiple people, when I switch between chats Teams sometimes places me well above the last read line
If I chat with 2 or more people, when I switch from one person to the other, it will often place the scroll bar well up above where the last read line is, so I have to scroll down. When I do, it often takes 5 or more seconds to load all the IMs I've already read as well as the new ones. I either see blank space or solid rectangles where the text should be until it actually loads.
This makes it difficult to maintain good flow during multiple conversations.
