My hunch is you won’t be able to check in via the app and you’ll need to get an override from the check-in agent at the airport. Thanks in advance.
if you really want to travel on your US passport you’d need an ETA. But why? Just travel on your British passport into UK. Of course you’ll have to travel BACK to US on your US passport… just like you do today…
