Everything has come to its usual state now. Simply upload your binary as you've been doing this while, and broadly classify IDFA in two categories:
publisher: You use third-party ad-networks library to display ad. Choose the 1st option in IDFA -> "Serve advertisements within the app". You're a publisher since you show ads, but do not perform advertising for your own app.
Advertiser: You use third-party libraries to track conversions for your app, as well as track 'goals' in your app. You directly do not show ads in your app. Choose the 2nd & 3rd option in IDFA -> "Attribute this app installation to a previously served ad". AND "Attribute an action taken within this app to a previously served advertisement".
Mixed: You track conversions for your app, as well as display ads in your app. Choose all three options.
