Network error but it is NOT- it's a Discovery error

Since early this morning I am unable to login to my discovery banking app. It continuously says "you might be experiencing a network error". NO network error on my side. I logged into my app last night and all was fine. Before you come with your did you login via Wi-Fi or data stories, I used ALL avenues. Mtn data. Telkom data. Vodacom data. I used 3 different Wi-Fi's. I deleted the app and reinstalled on 2 different devices. IT DOES NOT WORK!!!!! The most shockingly disgusting thing is that when I call customer service I am unable to speak to a consultant as I am sent an in-app authentication notification that I CANNOT authorize as I CANNOT log into my account. This is the second time this year I have experienced this issue. Please don't respond with the same scripted message you send to all customers complaining about this same issue. Resolve it. It is NOT my data or Wi-Fi. This is a discovery issue. I need to access my account immediately.
