To obtain the WhatsApp API, I had to set up a Facebook app using my phone number. Facebook required me to disconnect my number from WhatsApp during the integration process and then reconnect to WhatsApp afterwards. After I removed my number from WhatsApp and integrated it with the Facebook app, I tried rejoining WhatsApp. However, each time I attempted to do so, I didn't receive the expected OTP code, despite multiple tries with many numbers the same issue keeps. What could be the potential cause of this issue?
