Unable to log into App, but app works – BLACK+DECKER Review

I have an iPhone XS Max with iOS 12.4.1. I can log on to B&D website just fine but can NOT log in to app. It would say, “Could not complete request. Please try again.” Try to create new account with app, it will say same thing. Went on my old Android phone and was able to log in on app just fine. Love your products, and really want to love your app also. Please Help!!! I will still love your products!!!!
