Refresh Bank Feeds

My Zoho Books has two active bank feeds however these only sometimes refresh - I would say refresh has only occurred say 3 times when I have have clicked "refresh feeds" maybe 20 times. A message comes up that "Zoho Books is refreshing your feeds, this would take a while, you can continue working". When this message comes up, the bank feeds are never refreshed - it is only successful when there are "dots" escalating to show an action at the top of the page. I've tried logging out and in again and it doesn't work. How can I ensure that Refresh occurs whenever requested.
