Messenger Platform m.me links ref parameter is not sendt

Using node.js

If I use m.me link with ref parameter: http://m.me/mytestbot?ref=test

There is no sendt message on my webhook.

But if I use the url given to me inside the messenger: https://www.messenger.com/t/randomNumberString/?ref=test

There is a message with my referall parameter.

I have subscribed to messaging_referrals website in app settings.
