Since I updated to IOS13 our App hangs, the page and de Menu don't work, on IOS12 works fine.
I attach a simple code to try, simple press some times for example on zoom in/out and alternate with click on map, and the App hangs.
Toolbar tb = hi.getToolbar();
Image icon = theme.getImage("icon.png");
Container topBar = BorderLayout.east(new Label(icon));
topBar.add(BorderLayout.SOUTH, new Label("Cool App Tagline...", "SidemenuTagline"));
topBar.setUIID("SideCommand");
tb.addComponentToSideMenu(topBar);
tb.addMaterialCommandToSideMenu("Home", FontImage.MATERIAL_HOME, e -> {});
BrowserComponent browserComponent = new BrowserComponent();
browserComponent.setURL("https://leafletjs.com/examples/quick-start/example.html");
hi.addComponent(browserComponent);
hi.forceRevalidate();
hi.show();
