An application on Safari will not respond to signin data
An application on Safari (Version 14.0.3) will not recognize the sign-in ID & password. Google Chrome accepts the sign-in data. Have changed the ID & password without luck. Talked with IT tech of application company & he decided Safari the problem.
Have not found any other application that rejects the sign-in data. Does this refute the decision of the IT tech?
