Yeah, it seems the update killed the CO app. I too had been tracking my UA flights with the UA app and my CO flights with the CO app. I can log into the UA app with my CO OP number. I found this especially useful for mixed metal itineraries.

What would be ideal at this point is to allow a simultaneous dual log-in to both accounts. Just feed two streams of data to the rest of the app. That would *hopefully* be trivial to program and then would be even better than having 2 apps.
