Business Problem:
Duplicate contacts are created when numbers added lack an area code following the country code. This occurs despite initial contact through a WhatsApp template.
Use Case:
For contacts from Mexico, if the number added after the country code "+52" does not include the area code digit "1", the system creates a duplicate contact, even after a WhatsApp template is sent.
Desired Outcome:
Implement a feature to automatically verify and append the necessary area code after the country code when a new contact is added.
Example:
For contacts in Mexico, the system should automatically check for the presence of the digit "1" after the country code "+52". If absent, it should automatically insert the digit "1". This adjustment aligns with WhatsApp's requirements for Mexican numbers.
Workaround:
Manually append the appropriate area code to each number during import. The final format should consistently follow the pattern: +(country code)(area code) without the "1" after +52.
