Banking App locked or not working.

I received my card today and activated it in the morning. Later today, I tried to log in, the app is no longer working. I used my computer to log on, there was an error that I have insufficient details. I called all the numbers at hand to try and reach out to discovery for assistance but to no success. Also the voice prompt is asking to send the app authentication which is not helpful because its not working. The chatbot also could not help, why is it such a frustration to have this card? Is it difficult to get through a consultant who can assist without having to be verified through the app?.

I am not sure what to do now.
