How to Resolve WhatsApp Business Number Validation Issues

I’m having an issue and I hope you can help me. I’m trying to create a customer support agent for WhatsApp Business. I followed all the steps in the Meta dashboard to validate my number and set up the WhatsApp Business account that the agent in Lindy AI should use. However, the number is still showing as pending and hasn’t been validated. Could you please guide me on how to solve this? Thanks in advance!
