As stated above the red arrow, download cart is not supported post TS12, TANE and newer, which includes the TS19 you’ve mentioned you are using.I'ved tried again after a while and it worked this time. Another issue I've run into, however, is that whenever I try to download anything from DLS, nothing happens when I click the download button. I've also tried downloading individually via the content manager, but the button is also not doing anything. Is it an issue with the browser again?
