Tested on Twitch mobile app version 13.3.1
Steps to reproduce:
- Open the app and open a channel with mod role.
- type /announce or /msg command and add the text.
- Send the message.
The message is sent in plain text and does not trigger the command or a chat message is displayed that says “the command is not supported”
The message should trigger the command and show the message the same way as the web page.
