Not worth it.
Response from developer
Hi, what app are you trying to mirror? It might be that the app you are using is blocking screen mirroring. The best way to check if an app has blocked Screen Mirroring, is to perform a regular 'screen recording' selecting the camera roll as destination (not our app). If the recorded video shows the app you want to mirror, it works fine. If the video is empty, then the app you want to mirror does not allow Screen Mirroring. Unfortunately, this issue is out of our control. However, you should be able to mirror content from all other apps that allow Screen Mirroring. If you need any further assistance, please contact us either via e-mail (support@airbeam.tv), Facebook Messenger or through the “send diagnostic information” option in the app.
