Hello everyone,
It's 55hrs before my flight and right on cue I get a seat alert email from expertflyer. I have an exit row seat booked and EF shows that my entire row is now empty, including my seat. The other exit rows show occupied seats still.

Manage my booking on CX still show my assigned seat with confirmed status. I'd like to think that EF is wrong but is this a common occurrence? Sorry if there's another thread on this topic.
