Hi. I clicked the Whatsapp share button and it led me to Whatsapp. Good. Unfortunately, I noticed that my referral link broke after my domain for example, https://mysite.com is what can be clicked but ?afmc=1b cannot be clicked. With a forward slash before the question mark, however, the entire URL is clickable. Please, test this on mobile to see for yourself.
