Hello, Mrsruthsmall. Did you encounter any error message when you tried to reconnect your Santander UK account to QuickBooks Online (QBO)? If so, could you please share it so we can pinpoint what's causing the issue and give you the right resolution?
Since you've mentioned that Santander UK banks aren't available in QBO, I suggest checking their website to see if there's undergoing maintenance or if they're performing changes with their URL that's causing it to be unavailable in QBO.
In the meantime, you can manually upload your transactions to keep your books up to date. Once the reconnection is restored, please remember to review and exclude the duplicate ones so your totals stay accurate.
If you have further concerns, please feel free to reply to this thread. We're here to assist.
