How can I share contacts via WhatsApp on iPhone 16?

Using iphone, I have been sharing contacts via whatsapp years ago and the recipient receives complete details - such as name, address, company no., designation, email add, working nos., however, this past few weeks or last month....if I am sending, what the recipient receives is only the office/working/mobile nos. and the person's name unlike before. Can someone help me on this? thanks in advance.
