Thank you all. Figured out the issue and duh! it was that one member had set their digest to only following but they were not following anything so, no digest for them. So we set it back to all messages and hopefully that solves that. I had not thought to look in the advanced panel. My stupidity!
The other was bouncing and hadn't seen the message that was sent automatically to unbounce themselves. Once that link was clicked all was fixed.
So - all seems good now.
thank you!
