I was not able to use Screen Mirroring/Miracast directly from shortcut menu of my Huawei Mate 10 Pro. I thought this was because I am not using a 5Ghz WiFi.
Today I installed an app called “Miracast for Android to TV” on my Mate 10 Pro. With this app Screen Mirroring works perfect if started from the app.
The wireless Projektion button in the shortcut menu of my phone still does not work with the PPM. But it works with my fire TV Stick.
Do you think this is a problem of the PPM or my phone?
