Constant Contact advertises the ability to log-in to your accounting using your PayPal credentials. I set-up my account this way since it is desirable to have one less sign-in to remember. Early in 2018 the sign-in through PayPal ceased working. Since this was my primary account log-in I no longer have access to admin functionality (namely billing) in my account and have to call customer service regularly to manage my account whereas before it could all be done online.
Suggest either resolving this functionality gap or removing the option altogether.
