3. Scroll down to and click on portis button
4. Portis pop-up shows up, the recipient signs into his portis account
5. Recipient see balance on radicards page (still on the claim page) as 0.00eth
6. Recipient try to log into portis account from another browser (still on mobile), see balance on portis 0.00 as well
7. Recipient comes back to radicards website and then tried to click button 'claim this hongbao' again and it doesn't work anymore. It seems that the card hasn't yet been claimed but why the button is unclickable?
