If you changed the bundle id of the license key after created, the license key will be updated to a new one. The old one will still work for the unchanged part ONLY.
If you created key A with iOS: x, Android: yy, and in another day you change it to key B with iOS xx, Android unchanged, then key B will work in Android with yy and iOS with xx, but key A will only work in Android with yy and iOS with x, NOT in iOS with xx.
