For some time I've beeing using PlayerXtreme in order to watch
mkv videos on my iPhone 8 and I was able to drop them into it from my MBP using Airdrop.
But since iOS 13, my iPhone doesn't wants to save
mkv anymore and claims that I need to download an app to read them:
Similar to this question : Transfer MKV files to VLC player on iPhone using Airdrop
How can I save mkv files on my app using Airdrop ?
Note: I'm still able to save them using USB. I tried with KMPlayer, Infuse, VLC and the issue is the same. I'm on iOS 15.1 & macOS 11.6.1
Since iOS 13.4 I manage to use Airdrop to share
mkv still have the issue
