Hi @Ist126
If you want to switch announcements and conversations on your phone, you can try these steps:
- Open the MS Teams app and select a channel.
- Below the input box, select the format icon.
- In the box that pops up, select the arrow next to the new conversation, and then select Announcement or Conversation.
- Enter the message you want to post, and then select Send.
If you still can't switch between announcements and conversations, check if you have the latest version of the MS Teams app on your phone.
