Users on iOS can't write to group chat with a bot

Question

Hi all, I'm seeing some strange behaviour with the Teams iOS app when trying to interact with bots in 1-1 group chats . I've tried with multiple iPhones, all updated to the latest Teams version. The same issue does not appear on Android and Web/Desktop flavours of Teams. Has anyone seen this issue before? I couldn't find anything in the knowledge base

Setup:

A group chat with two participants: one bot, one user

Behaviour on web/desktop:

User sees both participants of the group chat, user can send messages in the group chat

Behaviour on Android:

User can send messages in the group chat

Behaviour on iOS (last tested with 6.13.1):

User does not see the bot in the participants of the group chat:

User cannot send messages in the group chat:

(also notice the bot, which is correctly named "Symlabs9 - Symphony" in the messages on web/desktop, is shown as "Unknown User" on iOS)

it seems Teams iOS is not counting the bot as a user? which would explain why the bot doesn't appear in the member list, and why the error about needing more than one person in the room is shown?

Meghana-MSFT&nbsp;Correct, we are using Graph API. First we create a chat of type group with 1 user ("Joseph" here)https://learn.microsoft.com/en-us/graph/api/chat-post?view=graph-rest-1.0&amp;tabs=httpThen we add the bot app ("Symphony" here) to this chat:https://learn.microsoft.com/en-us/graph/api/chat-post-installedapps?view=graph-rest-1.0&amp;tabs=http#example-2-install-app-in-a-chat-and-consent-to-the-resource-specific-permissions-required-by-the-app&nbsp;This works fine when the user (Joseph) uses web/desktop and on android - see the first screenshot. But when they are on iOS they can't send messages
