I have been trying for days now to connect my Santander account to the Quickbooks app but it won’t work at all, is there a way to fix it?

Hi kittyc-xo97-gmai, thanks for joining the Community - please try troubleshooting the connection by logging into QuickBooks through an incognito/private browsing window (press Ctrl + Shift + N to open on Chrome or MS Edge) ideally using a computer/laptop device if you have this available 🙂
