ISSUE
The currency code for one or more of your ViewContent events does not match an approved 3-letter ISO currency code. This may affect your return on ad spend calculation.
SOLUTION
Open your website's source code and locate ViewContent events using a currency parameter. Update the code snippet to include an approved 3-letter ISO currency code, such as USD or GBP.
