In the Tencent Cloud Chat SDK, the conversation management class is
V2TIMConversationManager(Android) or V2TIMManager(Conversation)(iOS and macOS). You can use the conversation management class APIs to display/update the conversation list, update the unread count, pin a conversation to the top, make a conversation draft, and mute message notifications.Conversation Class

In addition, if the information of a conversation has not been updated for a long time, this conversation can be stored in the cloud for at most 7 days. Therefore, local conversations displayed on different mobile phones may be inconsistent with each other.
