Suggestion: Please double-check that your uploaded CSV file is formatted according to Vapi's requirements—missing or misformatted columns can prevent the "Launch campaign" button from working. - Tip: Review the [CSV formatting best practices](https://docs.vapi.ai/outbound-campaigns/overview#required-information) and ensure all required fields (like phone numbers and names) are present and correctly labeled. If the issue persists, try re-uploading the CSV and refreshing the page before launching the campaign. Source: - [Outbound campaigns quickstart](https://docs.vapi.ai/outbound-campaigns/quickstart)

If the button is not activating, the CSV is not in the correct format. Please ensure that the correct column headers are in the file and that all of the numbers are in E.164 format
