Fiserv iOS Apps Log Passwords Insecurely

Background

The Fiserv apps listed below all have the same security problem--they exposes passwords in a log on the phone. Each link goes to a page detailing my test and notification actions. This practice is unacceptable for any app, according to the OWASP https://github.com/OWASP/owasp-masvs, specifically, this item:
2.1 MSTG-STORAGE-3: No sensitive data is written to application logs.
