{"error":{"code":"ConversationNotFound"

In one of my deployments I am getting this issue for a particular user. The user reported that they accidentally deleted the communicator chat and since then they are not receiving any new messages from the app and they cannot see the previous messages either. Tested this also by placing this user and a second user in a M365 user group and set it as the Target Audience in the Communicator app. The first user does not receive any message at all while the second user is receiving it just fine. They also seem to be not receiving any messages in the pinned communicator app that are sent orgwide.

I have checked the app registrations for the graph app and the supported account types was changed to Single Tenant, but after switching it back to Multi-tenant the issue still remains. The User and Author app registrations are set to Multi-Tenant as well. I have checked the Api permissions and they have been granted.

The Recipients status only shows the status of the message received successfully by the second user there is no entry in the detailed reports either if the message receiving was a success or failure.
