You should be able to use state filters in the lookalikes feature. The location filter accepts both cities and states - for example, you can enter 'Texas' as a location. You can specify locations when setting up your lookalike search filters, and you can also exclude specific locations if needed.If you're still having trouble using the state filter, please ask for human support to help troubleshoot the specific issue you're experiencing.
