When on MS Teams I used to toggle to browse mode and read all the chats using Shift + 4 or just 4 as all the chats used to be heading level 4. In an update done around last week, MS Teams no longer marks chats as H4. I need to arrow up/down to read the chats which is a very inconvenient and slow method to do. The focus mode did not work really well for me as there I do not have the capability to read the chat word by word or letter by letter if I want to.
