MobileFirst My migrated iOS project unresponsive if I extend WLAppDelegate, but not if I extend WLCordovaAppDelegate

Question

I've migrated 9 iOS Hybrid apps from MobileFirst 6.3 to MobileFirst 7.1 using MobileFirst Studio. 4 of the apps work fine. But the other 5, the UI is unresponsive to clicks. As part of the automated migration process, the headers of these 5 apps (only) were changed to reference the new WLAppDelegate interface. Strangely I've noticed that if I switch my AppName.h file from extending WLAppDelegate back to extending the original WLCordovaAppDelegate everything works fine. Why? I'd love to move off this deprecated code to your new WLAppDelegate interface.

My header and .m file match the defaults generated by MobileFirst Studio 7.1 when you request a new iOS app so it must be something else.

Here's my non-working .h and .m file

//
//  MyAppDelegate.h
//
//

#import <IBMMobileFirstPlatformFoundationHybrid/IBMMobileFirstPlatformFoundationHybrid.h>


@interface MyAppDelegate : WLAppDelegate <WLInitWebFrameworkDelegate> {

}

@end

//
//  MyAppDelegate.m
//  IssuesReturns
//
//
#import "IssuesReturns.h"
#import <IBMMobileFirstPlatformFoundationHybrid/IBMMobileFirstPlatformFoundationHybrid.h>
#import "CDVMainViewController.h"

@implementation MyAppDelegate

WLCordovaAppDelegate is a deprecated compatibility API to allow easier migration of pre v6.2 apps to 6.2+ apps. It can be used but the recommendation is to use WLAppDelegate.
