A linked family member or friend does not see the patient's app. They land on their own dashboard: the latest post from the feed (or an honest empty state), then big doors to share in the feed, send love to the Love Bucket, plan a visit, play, learn about aphasia and keep their own journal. Friends share to the friends feed and do not get the journal.
If a sign-in has quietly expired, that page says so loudly instead of looking like an empty app, with the way back in.
