I think many of my descriptions have the keyword more than 5 times without problems.
It all matters if you write naturally good descriptions, or keep repeating same thing that makes not much sense.
My descriptions are human-readable ( I mean that a person will read it and will really understand what the app offers).
If you reach a human tester of the app, this makes a big difference.
The app is published now fortunately. It was a copyright issue but I'm puzzled as to how the bot flagged it. That's why I thought it was keywords. Bot flags for keywords and then human bans it for another reason. Maybe they scan images for copyright? Idk, but I know that in the past you could publish without a human ever seeing it.
