What is chat disabled due to missing profile public key?

This message typically appears when the chat client is unable to establish a secure connection with the chat server. This can happen if the user's profile public key, which is used to encrypt all communications sent from their device, is missing or corrupt. When this occurs, the chat application will disable the chat feature until the public key can be restored or regenerated. The user will need to generate a new public key by accessing their account settings within the chat application and following the prompts to create a new key. Once the new key has been generated and imported into the chat client, the user will be able to resume normal chat operations. It is important for users to regularly backup their profile public key to avoid the loss of their chat history and to ensure that they are able to securely communicate with other users in the future.
