Agloperena

I've been using the application for years, I've never had problems until more than a week ago. It does not allow me to enter the application, I have deleted the application I have reinstalled it, I have called and so far it seems that they do not know why and they have not been able to solve the problem. I use the application to make payments and check the bank statement. When I try to enter, it tells me an authentication error. I need to know who can solve the problem.
