I know this is not the place to record bugs, but the UK phone support people refused to record it and explicitly told me to record it here.
When using 4k monitor resolutions (3840x2160), the Incoming Bank transactions shows on load the 1st N transactions. On hi-res monitors this does not fill the screen and thus there is no scroll bar. This bricks the lazy-loading of subsequent transactions as you cannot scroll down the page and trigger the JS scroll events.
This stops the user from seeing all the transactions. If you shrink the browser window or move it to a smaller monitor, then the functionally start to work again as the scroll bar is enabled once more.
This was repo'ed on Chrome on Windows 10.
