None of this works unfortunately. The connection had been working perfectly well until 3 days ago.

When I try to update my bank account transactions, I go through the multiple steps as usual with OTPs etc (this has always worked), but then I get asked to re-enter my login details. I have also done this multiple times, but I just get stuck in a loop of the system asking me to re-enter my login details again and again. 

I have double and triple checked that I have entered the correct login details, and also that my online banking is working properly.

I had a conversation with the help desk yesterday and they told me that there was maintenance going on at OCBC, but I am not convinced that this is the case as the issue has been persisting for over 3 days now.
