I recently attempted to delete a phone number from one WhatsApp Business Platform Account (WABA) and assign it to another WABA. However, when trying to use the deleted phone number with the new WABA, I encountered the error: 'Please double check that this phone number is registered on a WhatsApp Business app account.' Could anyone explain why this happens? Is there any way to resolve this issue or reuse the deleted phone number in a new WABA?
As per the error message, the phone number is still connected.
Please perform wa.me/thePhoneNumberHere and check if you receive an error message saying the number isn't on WhatsApp or if you can interact with it. If the second case is true, It means the number is connected
I checked, and it's showing an error: "Phone number shared via URL is invalid," which means the phone number isn't connected. However, when I try to add the phone number to the WhatsApp Manager account, I encounter the same error: "Please double-check that this phone number is registered on a WhatsApp Business app account."
