I am having a similar issue with connection to my HSBC business account and its been going on now for about 4 months. I have on a number of occasions tried to use the online support service but get nowhere. i explain the issue and about 2 days later get an email to say my problem has been resolved but it hasn't. 

It is so frustrating. if i delete the app I will loose months of receipts and transaction information. please fix thius issue!!

it would be helpful to speak to a human being about this.
