I want to download ertflix app on my Apple TV box bit doesn’t appear on the App Store. The same app though I was able to download to my iPhone

just because an app is out for iphone or ipad does not mean there is an appletv version

the developers has to take actions to support all platforms from phone, to tablet to tv to watch to mac

it does not appear that the Elliniki Radiofonia Tileorasi S.A. took such measures

ERTFLIX on the App Store (apple.com)

The ERTFLIX App is now available on the Apple App Store for the Apple TV. However, after downloading the app, I am unable to open it. Can’t understand why. The app will open for 2-3 seconds and then close. I have no problems with the Roku device on a different TV, but can’t make it work on the Apple TV streaming device on my new Sony TV. Any help is appreciated.

Update: after contacting ERT they updated the ERTFLIX app, and now works fine on Apple TV.
