I testing Visa Direct POST Fund Transaction with a valid test data set in Visa certified environment (cert.api.visa.com)
and today all responses are 202 Accepted. Is the environment overloaded or it is related to the data? In previous days I had no issues with the same test data, and the responses were 200 OK.
