Hi guy22,
Hope you are well. I looked into this for you and currently we do not have a connection for Bank Feeds for a Latitude Gem Visa Credit Card. However, I can certainly add them to the request list for you.
In terms of having your Bank Transactions in QuickBooks Online you should be able to export your transactions from your online banking to a CSV file and then you can import them into QuickBooks Online.
Please see the below article which outlines how to do this:
Import Bank transactions
Thank you,
Kay.
