In an email from Apple to developers, it says that all Apple Search Ads campaigns running on the App Store in Russia are currently on hold.

No new campaigns will be eligible to run on the App Store in Russia for the duration of the suspension. When the suspension will end is highly unknown.

Apple has already made a number of moves in an effort to stand against the Russian invasion. Last week, Apple ceased product sales in Russia and pulled two popular apps from the App Store. The Cupertino company is also matching employee donations to Ukraine on a 2:1 ratio and taking donations on its website and App Store.
