Participant projected address not provided

This is a Group MMS conversation, but the given participant has neither an Address nor a ProjectedAddress.

• You may have inadvertently provided an Identity (chat user), rather than an Address (mobile phone).
• You may have mistyped or inadvertently left out the ProjectedAddress parameter.

• Provide a Projected Address when adding this Participant to the Group Conversation. This is the correct path when adding Chat participants to a Group MMS conversation.
