I have tried connecting my old sprocket multiple times to my new iPhone 11 pro max and it doesn't seem to be connecting to the app. It connects to my Bluetooth settings, but as soon as I go to print something, it says that it needs to be connected to the app and that it can't find the printer. So I dosconnetcted it from the new phone, connected it to the iPhone 8 of my wife and it works perfectly. Why? Is there any issue with iPhone 11. The app is updated to the latest version.
