Guys is it possible that the wallet is not working correctly ? I wnt to sell on cryptox, I go to send amount of Gbyte and type in the icon on top right corner to scan a QR code provided for deposit by cryptox .. It doesn't respond nor work for me... Anyone know what the issue is

Can you please describe your issue with more details? Is it your first time on cryptox? There used to be a bug (maybe it's still there) that for displaying the correct QR code, you had to log out and log back in, maybe that's what you are facing ...
This has been the issue. Please report for fellow new users in upcoming events. I had to relog to make it work after activating my stuff !
