Bug iOS 5.1

Loved the app before updating.
Definitely like that the iPhone app does NOT allow access to the console master layer as the phones are used by musicians onstage and DEFINITELY dont want them to be able to "accidentally" begin remixing the house...lol
Updated console firmware to v2.05 and had to update iPhone app. iPhone 4s running iOS5 (DO NOT WANT TO GET INTO THE "iOS upgrade loop"...my phone works FINE for everything else I use it for)...
...Anyway...
Upgraded the app and everything was tres cool hunky dory all good...
Next time I tried to use the app it worked fine until I rotated the phone into "landscape mode"to access the bus mix fader layer...and it quit immediately upon rotation.
As I stated before ...the app worked fine for the 15mins I played with it after the update, so this should be a minor bug fix...but it is pretty much useless now. Id be willing to upgrade my iPhone to iOS6 but the only update offered now is 8 and I prefer the look and feel of my phone now.
I firmly believe the app bug should be addressed because I have several musicians who feel the same way I do about "constant software upgrades" and the compatibility issues they lead to...besides...if you have 6 musicians onstage the odds are they are NOT all running the same iOS.
A bug fix here for iOS 5.1 would be GREATLY appreciated as Im certain its something minor since it worked just fine initially...
