Ad targeting options greyed out

When you want to assign an ad with multiple languages to an ad set and that ad set has been greyed out, the reason behind it might be the ad set placements you've chosen.

Multi-language ads can only be used together with audiences including the following placements:

  • Facebook: Feeds
  • Facebook: Right Column
  • Instagram: Feed
  • Audience Network: Native, Banner and Interstitial

The solution is just making a different ad per language or simply use the correct placements.
