Environment Details
The AWS Secret key field is not displayed on Amazon S3 connectors. This is reported on an external monitor with a 2496x1664 resolution that is the recommended display resolution. Using the recommended scaling or changing the scaling to 100% or 125% does not address the issue.

Cause
GCSE-204/GDC-1199 has been logged to address this issue.
Resolution
As a workaround to enter the AWS Secret, please do the following steps:
1. Select the "Display XML Properties Windows" option found in Designer > Options > User Settings > Edit User Settings.
2. Once this is done, on the Amazon S3 connectors, click the XML view and select Edit. Add the Secret Key in the <SecretKey> tag. Example:
<SecretKey>xxxx</SecretKey>
Enter the value for the rest of the fields in the user interface.

NOTE: The Secret Key field will be encrypted. Hence, the value may be different from what was first entered.
