If Label Z and Label Y claim an asset in the same territory, but Label Z has a match policy of Block and Label Y has a match policy of Track, which policy will YouTube apply until the partners resolve their ownership conflict?

YouTube prioritizes the most restrictive policy in cases of conflicting claims to prevent potential copyright infringement. Since "Block" is more restrictive than "Track," YouTube will apply the "Block" policy until Label Z and Label Y resolve their ownership dispute. This ensures that the content is not monetized or tracked without clear ownership, protecting the rights of the party with the "Block" policy. "Track" would allow the content to be viewed, which conflicts with the "Block" policy. "Monetize" is less restrictive than "Block." "Both Block and Track" is a contradictory state and not a valid policy application.
