I haven’t permission to push and create PR. How can I get them? Just change from at MvxSplashScreenAppCompatActivity and MvxSplashScreenActivity

protected virtual async Task RunAppStartAsync(Bundle bundle)
        {
            var startup = Mvx.IoCProvider.Resolve<IMvxAppStart>();
            if (!startup.IsStarted)
                await startup.StartAsync(GetAppStartHint(bundle));
        }

protected virtual async Task RunAppStartAsync(Bundle bundle)
        {
            if (Mvx.IoCProvider.TryResolve<IMvxAppStart>(out IMvxAppStart startup))
            {
                if (!startup.IsStarted)
                    await startup.StartAsync(GetAppStartHint(bundle));
            }
        }

Can anybody create this PR?

As I understand, SplashScreen uses Mvx.Resolve<IMvxAppStart> in several places, fix was made just for one place. One workaround - override RunAppStart in SplashScreen

protected override void RunAppStart(Bundle bundle)
       {
           if (Mvx.TryResolve<IMvxAppStart>(out IMvxAppStart mvxAppStart))
           {
               if (mvxAppStart.IsStarted)
                   return;
               mvxAppStart.Start(this.GetAppStartHint((object) bundle));
           }
       }

Yes, I think that should be sufficient to resolve this issue. @haohighview would you be kind enough to raise a PR based on the suggestion made by @nmilcoff
