Can we run re-engagement campaigns on iOS SKAdNetwork traffic?

Apple currently doesn't support retargeting measurement via SKAdNetwork. In addition to Apple's policy, most of traffics from devices running on iOS 14.5 and above don't include any advertising IDs, so the size of retargeting audiences can be highly restrictive.

What is the best way to map the SKAdNetwork Conversion Values?

That depends on your business model and campaign goals. Consult with your MMP partner to find the best conversion value model and then map the conversion values. Regardless of the mapping method you choose, you can easily set up conversion values in your Moloco dashboard. Be sure to check out our detailed guide to registering SKAdNetwork conversion values.
