Screen Mirroring+ for Fire TV 4+

I can stream the videos from my iPhone to my fire tv but I m not sure about the sounds as it plays sound only from phone and not the tv .. which makes it difficult to stream movies and videos from phone to tv. Can u fix that ?

Thank you for taking time to review our app. We apologize for the inconvenience. The TV Mirror App is still under development and currently does not support sound, but we are already working on it. Please stay tuned. You can connect your smartphone to a bluetooth box and temporary workaround this problem. Please let us know if this works for you. We'd love to hear from you.

The app is doing good image mirroring but it hangs a lot and besides that there are two more flaws, even after good internet speed and the internet transmitting device kept close to the devices mirrored, the video hangs and stops and does not mirrors properly.
When mirrored I can’t hear the audio from TV but I hear it on iPad or iPhone and if I mirror though iPad the screen mirrored does not stretch on the complete tv screen but when I do with I phone it covers the entire screen..
Developer, as the app is still under development, I believe you will work on the above issues.
Thank you!

The Screen Mirroring App is still under development and currently does not support sound, but we are already working on it. Please stay tuned. You can connect your smartphone to a bluetooth box and temporary workaround this problem. Please also make sure that the energy-saving mode of your phone is not activated. This can lead to incorrect transmission.

It would be also very kind of you, if you could add a few more information: When exactly does the problem occour? While mirroring a specific app or a specific website? Or while playing a local video? More detailed information will help us to fix and improve the app. Thank you very much in advance. Please note that issues may occur during an update process of fire tv.
You can check if this is the case as follows: Settings ➨ My Fire TV ➨ About ➨ "Downloading update". Please also try to switch between 2,4 GHz and 5GHz wifi network as due to different conditions the different frequencies could work better or worse. Please let us know if any of this solutions work for you. You can also reach us via E-Mail (info@video-tv-cast.com). We'd love to hear from you.

Share screen is good but audio plays from Mobile only.
