Just bring back the old chat.
I get that the new chat isn't finished, but maybe just leave the old one in place until you have finished coding the new chat. The new chat system is garbage. (Can't upload images. Can't reply to another manager. Can't access from the website. Can't like/promote another manager's comment.) Seems like the old one was functional, at least. This one needs to spend some time in beta testing before being pushed to everyone.
We’re still working on improving and updating Fantasy Chat. A lot of the features you mentioned are coming. You can read more about them here https://help.yahoo.com/kb/SLN29281.html
