On a flight standby - app doesn't know I'm here
I flew stand by on an earlier flight. There was a weird mix up where the GA actually gave me someone else's boarding pass and I didn't notice. I used the paper pass. Other passenger used the digital pass and of course we realized it when we both were trying to sit in the same seat. Meanwhile my digital pass still said standby. It wasn't a full flight so they just told me to sit down in a nearby empty seat. Now the app has my original boarding pass showing. Do I need to do anything or will it sort out on its own?
EDIT: FA says they know. 🤷
