Hi, we started noticing this same issue with the Information Lookup solution. We are using it to serve general parcel, address, structure and zoning information to the public. We like the attribute consolidation into a single pop-up. Windows 10 Desktop and Android devices, the app works great. After much testing, the app works on iPad but only in portrait mode. If the app is started in landscape mode, the app refreshes repeatedly and then crashes. If the app is started in portrait mode, app works fine. If we then rotate to landscape mode, refresh the browser, the app crashes. This occurs with the Safari and Chrome browsers. Of course, the app looks better and is easier to use in landscape mode. I do have a custom basemap I created for the reference layer. I have now replaced it with an Esri basemap and am testing now. Thanks, Jay
