"You cannot send messages to this bot" - Chatbot issue with the new Teams

[Tran_Tuan_Minh]

We have a Teams chatbot which works normally with the old Teams. But if I change to the new Teams, the chat box is disabled and it shows the message "You cannot send messages to this bot". So is the issue due to new Teams bug or is there any new configurations that we need to apply for the chatbot to work with the new Teams?

I am old teams but current channel. And one of my admins is on new teams. Both are having the same issue and it stopped working. However the phone app is working. Few others are reporting this issue as well, hope MS heard this and does something. Check
