Now that I've gotten Flash Builder 4.7 to work with OSX 10.10 Yosemite (*see below) I find the ipa no longer installs on my iPad via iTunes. The icon shows up but stays dim.
The app compiles and runs ok in the iPad simulator
This is one day after having the app accepted into the app store--no way to celebrate!
* this got FB 4.7 running for me
