My wife's MagSafe updated instantly when connected to M1MBP, which is connected to Internet but not on its own charger. But can't get mine to update at all. tried M1 MBP, M1 Air, iPad Pro. It shows up in Settings > General > About so don't think it is a fake. It is on 247.0.0.0. Saw two people say they were on 174.0.0.0 earlier in thread which is puzzling.
