Please see my post
here with a couple of weird issues with the android app.
Also, I've had a lot of difficulties with changing award itins. Twice I've gotten a message instructing me to call to finish ticketing the res. At least it's actually a more informative message than the "We've hit some turbulence" one.
After acknowledging the message then I am taken back to the Details page and the "Request Upgrade" box is visible.
When speaking to a phone agent, she said it has something to do with the ticket change and the upgrade happening simultaneously and stepping on each other. The agent had no problem ticketing and processing the upgrade.
