One thing I forgot to mention, this only happens on devices, it appears to be working on the simulator.
I've tested with monotouch 22.214.171.124, and the search now works correctly on 64-bit devices.
However now the app doesn't launch at all on 32-bit devices (https://bugzilla.xamarin.com/show_bug.cgi?id=24507).
Can you check again now that bug #24507 has been fixed?
Hi Rolfe, that bug has been fixed.
Closing then. Thanks.
*** This bug has been marked as a duplicate of bug 24507 ***
Hey Rolfe, bug #24507 has been fixed, but this particular bug is still happening on the latest build of Xamarin.iOS 8.4 (126.96.36.199). Should we leave it since it works correctly on 8.5?
