Trouble with a share sheet on a sheet in iOS 15

I've got a Preferences system that I've implemented as a sheet. Within that I have an export command that bundles up some data and then offers a share sheet. Under iOS 14, I could trigger this share sheet from the onDismiss handler in the Preferences sheet call. Under iOS 15, it appears that onDismiss executes before the Preferences sheet goes away, so my Share Sheet never appears.

Here's the code that activates the Preferences sheet, which includes the onDismiss handler:

.sheet(isPresented: $theCurrentLog.prefsAreVisible, onDismiss: {
      if currentPrefs.thePreferences.exportToShare {
          let av = UIActivityViewController(activityItems: [currentPrefs.thePreferences.exportURL], applicationActivities: nil)

UIApplication.shared.windows.first?.rootViewController?.present(av, animated: true, completion: nil)

      if UIDevice.current.userInterfaceIdiom == .pad {
            av.popoverPresentationController?.sourceView = UIApplication.shared.windows.first

                    av.popoverPresentationController?.sourceRect = CGRect (

                        x: UIScreen.main.bounds.width / 2.1,

                        y: UIScreen.main.bounds.height / 2.3,

                        width: 200, height: 200)

                }

                currentPrefs.thePreferences.exportToShare = false

            }

            let prefsToSave:APreferenceSet = APreferenceSet()

            prefsToSave.thePreferences = currentPrefs.thePreferences

            prefsToSave.savePrefs()

        }

        ) { Prefs()}

That exportToShare boolean in the if statement is set inside the the Preferences sheet.

Again, this all worked under iOS 14. Any ideas how to fix it for 15?

Thanks

I switched to the Activity Sheet code that I found here:

And now I've got no problem bringing up a Share Sheet over my other sheet. However, I'm having trouble getting it configured to share what I want. I'm trying to share a zip file out of my app. I've got an NSURL to the file, which I can pass with no problem, but it fails when I try to airdrop it. I assume this has something to do with applicationActivities?
