Hello i need help
I bought the iPhone 12 mini a few days ago and wanted to make private mp4 films on my mobile phone via iTunes.
Unfortunately, when I open iTunes the following message appears.

You have to download the TV app or the "Video" app from the App Store for your iPhone in order to be able to synchronize films and TV shows.

Only in the App Store can I not find a video player with the name "Videos" but only video editing programs
I have already installed the VLC player, but the media library is empty when I open it.
What do I have to do to be able to play videos on the iPhone 12 mini.
I had no problems playing on my old iPhone 6S

Warm greetings
Markus
