The Skillz Platform uses the Advertising Identifier (IDFA) in order to serve advertisements within the app, attribute the app installation to a previously served advertisement, and attribute an action taken within the app to a previously served advertisement.
When submitting to the app store and asked about IDFA, make sure to check all boxes as shown on the screenshot below.
Skillz does not export encryption and so you should make sure to answer 'No' on this section when submitting your app to the Apple Store. Below is a screenshot for your reference.
When you submit/resubmit an app to the app store we recommend you include these reviewer notes along with your app. Skillz uses this living document to help you with your app submission and actively updates it.

Test credentials for Skillz tournaments:
Modified: June 24, 2016
In accordance with Section 5.3.4, skill-gaming competitions (powered by Skillz) are geo-restricted to players located where competing for real money in skill-based games is legal. Because the game also includes free tournaments that do not have cash prizes, the app can be accessed from anywhere but users in prohibited jurisdictions are blocked from entering real money competitions.
In accordance with section 11, the game’s multiplayer functionality allows players to deposit money into an account for competing against other players for real prizes (where allowed by law). The deposited money is not a virtual good and cannot be used for the purchase of virtual goods.
With respect to 3.3.12, the advertising identifier is used to serve ads at the end of free-to-enter practice tournaments and needed for performance attribution in our user acquisition campaigns.
