Currently toggling 'DND Incoming' does not stop contacts from continuing to message you via certain channels (Instagram, for example).
For businesses with a mix of personal & business messages, this means there is no way to stop personal messages going into GHL conversations. You can select 'DND Incoming' on friends/family messages, but it does not actually stop future incoming messages.
DND Incoming should apply to all incoming channels, or there should be a DND social / Mark As Spam option.
We need some way to block certain messages from coming in as conversations.
