When I bring up the Legacy / Family search page ,Family search is telling me that an ID person does not exist .
This person does exist in Family search and all details are the same.
This is happening to a lot of my nearly 3000 searches
You may need to contact the Legacy customer support group as this may be a problem from their end, or maybe they would be able to help you if there is something that is missing. I know that when I have had issues with Roots Magic, the customer support people have been really helpful.
