A. 1. Check App Settings: Look for any settings related to chat history or logs. Ensure that chat logs are set to be saved and not automatically deleted. 2. Update the App: Ensure you are using the latest version of TruMate, as updates may fix bugs related to chat logs disappearing.

B. 3. Backup Chats: Regularly back up important chats by taking screenshots or copying text to another app to prevent loss.
