Who do i contact regarding an apps suitability for device

On the App store, the game Kiss of War, from Tap 4 Fun (Hong Kong), lists compatibility for ipad 9th generation, it lists devices and ios required.

Since moving the game from my older ipad pro to the new ipad 9th gen, the game quits constantly.

KOW support have informed me the only way to run it on an ipad 9th gen is in low graphics mode and as the only app on the ipad, furthermore, listing a device as compatible does not mean it will work fully, 'it does not mean it will not freeze or quit'.

Personally this would not be how i deem 'compatible' to mean, i suspect for most users we would expect the game to work, not quit out every 5-7minutes.

I would suggest that the list of devices on the page is vetted and some updates placed on the page that state the truth that the game is so RAM heavy, running on not fully optimized servers (I have this in chat from their support and can share), that it will not run smoothly, as currently it feels the list of so called compatible devices is not an accurate reflection and miss-leading.
