I'm afraid this won't work, since it is not possible to install apps on the TV.
I also like to have this PN, please. Thank you
What PN do you mean? It will not be possible to install apps on these TV's, the only way to achieve this is to connect an external device like a Chromecast or something like that I guess.
Look at messages 3 and 4, please.
As has been mentionned a few times here already, it is NOT possible to install any apps yourself on a Medion TV. Your best bet would be to connect an external device like a chromecast for this.
