Urgent Facebook Ads Issue Fix

I'm encountering a problem with my Facebook account where I can't boost a post due to the Publish button being greyed out. It appears to be linked to my WhatsApp number being connected to a personal account rather than a business one. Time is of the essence, so I need someone with expertise in Facebook Ads to help me resolve this issue as soon as possible.

This job will likely involve:
- Troubleshooting the issue with the greyed out Publish button
- Possibly assisting with the verification of my WhatsApp number with Facebook for Business

Skills and experience that will be beneficial for this job:
- Deep understanding of Facebook Ads and its functionalities
- Experience with personal and business Facebook accounts
- Ability to troubleshoot technical issues quickly
- Previous experience in verifying WhatsApp accounts with Facebook for Business

I would like to keep my WhatsApp number as a personal account, so please do not suggest converting it to a business account.
