The app review we submitted was rejected:
Guideline 5.3.4 - Legal - Gaming, Gambling, and Lotteries
Your app offers skill-based gaming, which is not legal in all of the locations where your app is available.
Next Steps
To resolve this issue, please revise your app to:
- Restrict the locations where your app can be used
- Restrict the sale of your app to only the appropriate territories in App Store Connect
What should I do to pass the review?
You need to find which are those countries where skill-based gaming is forbidden.
This could help as they provide such a list of countries (to be checked) : https://docs.skillz.com/docs/legal-skillz/
Then, remove those countries from locations where your app is available.
Indicate, in the comments to reviewer, what you have done to comply.
