My apartments are in a location with WhatsApp is the primary phone service used, and my tenants are from all over the world. I cannot add their phone number to the tenant contact form as there is data input error for non US phone numbers. Can you change this error check to allow a country code and phone numbers that are not US based (including numbers that are not 7 digits long? Many countries have phone numbers with 6 or 8 digits after the country code)
