I updated all the 787s and the United and EVA 787s won’t show, as well as probably the new call signs. The only thing that has updated is the coat of arms added to the BA 787-10 and the NAV lights being fixed.
Just Restart your device. It should work. If that doesn’t work delete Infinite Flight, and then re-download it. Then restore all of your purchases and it should work. If that doesn’t work, then contact support.infinite-flight.com.
