I upgraded the app (iPhone) and it still has the other cabins grayed out on Delta mainline flights.
For some reason on my return flight this Sunday I got bumped out of my aisle C+ bulkhead seat into a Window seat still in C+. Since this is a connection carrier I am able to see the other cabins and noticed an entire exit row is open and selected the aisle exit row and it is telling me I can only select seats in my ticketed class of service
