why linked Amex transactions are showing as USD not CAD?

Your bank account may be set to USD, which is why the transactions are displayed in USD instead of CAD, @kalwatar.

If your connected bank account uses foreign currencies, you'll need to add those transactions using the appropriate currency. Here's how:

1. Navigate to Transactions and then select Bank transactions.
2. Open the For review tab, click on the transaction details, and choose Add.
3. Input the foreign amount or exchange rate provided by your bank in the currency fields.
