How to Get Old Game Day Notifications

A lot of people seemingly who have had them have been getting little pass blasts about decades old games. Play by play as if it's happening right now. I don't know why it's happening, whether they were just updating something on the back end. This just seems to be sort of random like it's games that don't have play by play data or public play-by-play data. But it seems like kind of fun. Like I almost wish I were getting them. Or maybe that should be a feature that you could opt into like give me notifications from past seasons as they were happeningright now.
