how do I cancel

This is a reply from this thread, Quicken daily download for Apple Card - Apple Community

“I did find a temporary solution for this and want to share in case it helps others:  I installed Mint, which accepts daily transactions. Then I downloaded a free Quicken Importer from http://www.quicknperlwiz.com/. So every day I open Mint & Quicken, then run the QIFImport which has a mapping to my apple.card.com account in Quicken and it pulls in the daily transactions for me. It's a few more keystrokes but in the end, it takes about the same amount of time as waiting on the Quicken Auto-downloader each day takes.“
