My son has disappeared from my People album after upgrading. It now shows his brothers face in induvidual portraits. When he is in a group (eg with his brother and sister) it will just identify two people and won’t show him with a question mark, even though the photo is full face and clear. Is there anything I can do - I search for photos of my children using People all the time. Thanks

Photos may have merged his album with the album of one your other kids, probably with his brother.
You may want to check the albums of your other kids or of other people where he is shown together, if you can find the photos of your son in their album.
Then you will have to split the merged album again.
