If you're having issues then take a look at the possible solutions below.
“What is a cache? And why do I need to clear it for online banking?”
The 'cache' is a bit like a folder that sits on your device and stores the details of the sites you regularly access. It stores these sites in order to speed up the page loading process when you revisit them. However, with the majority of sites being updated regularly, the information stored in your cache can become dated.
This can cause delays and slow down your online speed. Clearing your cache can often fix any issues that pop up. Each browser is different, but you can find where to clear your cache by clicking the ‘help’ menu on your browser and searching for ‘clear cache’.
“What are cookies? Do I need to clear them for online banking?”
Cookies are files that are saved on your computer, representing settings that you selected when using the browser. Any time a site asks a user to select preferences, there's a good chance those preferences will be saved in a cookie. As sites update over time, saved cookies can become obsolete or not communicate well with newer system updates, causing issues with how your browser interacts with the site.
Because sites change over time, when a site is updated, the cookies saved may no longer work so well with the website. Each browser is different, but you can find where to clear your cookies by clicking the ‘help’ menu on your browser and searching for ‘clear cookies’.
