CKA PSI plateform bad experience

Hello,
during my exam session I've encountered issues when arrived to 10th question , the copy paste didn't work anymore , ctrl+shift+v didn't work , and there was a display grey window that appears everytime that I tried to tap on the terminal , it was blocking me to advance forward on my exam till remaining time ( 90 mins ) has passed , the proctor and support was not able to unlock the situation so I didn't finish the exam , all they had done was to create a support ticket .. I've created a jira ticket for support team too https://jira.linuxfoundation.org/plugins/servlet/desk/portal/15/TCCS-62932 , I hope it'll be treated soon and I got a guarantee to another retake . Awful experience ..
