Lightroom People Find Not Working Cloud

After uploading several images to the Cloud, Lightroom "People" was able to find "some" faces. However, the people in the query all were taken during the same event. The images uploaded spans several years. One of the person who was overlooked and was in this event a in hundreds of other images over 25 years was missing. In the end when I went back "No People Found" Synched photos would be analyzed in the cloud. Be sure to check back later"

Lightroom ver 8.3, Build 250414-1406-5ace587
