Hi Team, I am getting error that voucher code is invalid error when trying to register for "Databricks Certified Associate Data Engineer Associate. I got this issue once page was reloaded due to slowness of the internet before checkout. and the voucher code I have received on May 12,2023. I have not used this voucher until today and I'am aware that It's going to get expired by Oct 1,2023. Can you please help here. Thank you.
