[Resolved] Affected CIMB Credit Card Channel on Chrome 66

Please be informed that due to the latest Google Chrome update to version Chrome 66, any Symantec SSL certification issued before 1st June 2016 will be blocked.

With regards to this matter, CIMB Symantec SSL certification was issued in May 2016 and it caused CIMB credit card unable to go through 3DS One-time Password (OTP, aka SMS TAC) authentication. However, CIMB debit card will not be affected.
