Screen Mirroring funktioniert nicht

Mirror photos, videos, games, websites, apps, presentations, documents and spreadsheets on Fire TV. * Supported Fire TVs: Fire TV Box+Stick, Fire TV Cube and all other devices of the Fire TV Family. * Your iPhone/iPad and your Fire TV must be connected to the same wifi to enable screen mirroring.  Screen Mirroring for Fire TV is the easy screen mirror app to share your iPhone or iPad screen on your Fire TV.  Please use Bluetooth speakers as a workaround. * Black screen issues: Some third party apps prevent screen mirroring.  It's the most advanced screen mirroring solution with zero delay and the highest screen quality.  When you try to mirror them, you will just see a black screen on your TV, for example with Netflix and Disney+.  Disclaimer: This app is not affiliated with Amazon or any other trademark mentioned here.  Please do not use VPN, Proxy, VLANS and Subnets. * Sound is not yet supported, but we are working on it.  This is a restriction chosen by Netflix and others, so we cannot fix it at the moment.  If you like the app and our constant work on it, please give the app a positive rating on the App Store.  Many thanks in advance from the development & support team.  This app was not created or endorsed by Amazon.
