I would like to suggest you for registration visit directly hunnyplay.io without using the link on thread because I think there is a problem with that referral link I have successfully register with this process. Hope this will also work for you. 
Maybe you should be a member of their support team because your suggestion worked for me, and the verification took less than two minutes via this method. The referral link has to be fixed to prevent the failed OTP verification form discouraging new people from the platform. Not many gamblers will have the patience to keep trying to sign up for the platform after a few failed attempts, some people will not contact support for solution, but will quickly move to the next casino option that they have.
Yes, I believe it has to be replaced since the referral link comes from the team link it is an indicator if they are getting leads from their announcement so it is better to have it replaced and have the leads counted that will give them a comparison when they launch their signature campaign.
The referral program is awesome of course you have the option to share your profit with your referrals and they have a lot of materials to use on your promotion, a good referral program and a long-term signature campaign will give them a lot of good leads.
