I get similar behaviour on the framework 13 amd with ec3.03 watching the EC console I see no events for when it’s been booted powered from the left PD port after an unplug. I get an event again from the right. But it’s not complete and there is a TODO message in the EC console about implementing PD port switching logic. Suspending unplugged seems to bring proper AC powered messages back again after resume when plugging on either side
