Google Messenger issue "couldn't download"

Not sure what the issue is, never had the problem until today, but using Google Messenger with Nexus 6P and now when my wife replies to a group message (same group message we have used for months) I am getting an error back to just our solo thread saying “couldn't download message, tap to download” but nothing happens. I am getting the other party in the groups messages and my wife and the other party can see mine and hers, but I can't see hers.

Any idea why? I haven’t changed any settings and like I said, this was never an issue before. I tried to clear the cache and data and nothing.

Thanks!

EDIT: Seems to be only when my wife replies to the group message. We have tried two different group messages and I get the other parties text, but when my wife replies, her says "couldn't download" and goes individually to me. But the other people in those groups are getting her messages. Thoughts?
