Transactions can have only one foreign currency at a time.

Hello info-accessaccou!

Thanks for posting here. Let me assist you in fixing this error in adding transactions.

This could be a result of a browser error. You'll want to use an incognito window and review the transactions from there. Incognito won't save your browsing history which can result in an error.

These are some of the shortcut keys:

• Google Chrome: Ctrl + Shift + N
• Safari 11 or newer: ⌘ + Shift + N
• Mozilla Firefox: Ctrl + Shift + P
• Microsoft Edge: Ctrl + Shift + P  

Also, you'll want to clear the cache and make sure you're using a supported and updated browser. This can fix any browser-related issues.

If this error persists, it's best to reach out to our Support Team so they can investigate it:

1. Click the (?) Help icon and enter Talk to a human (then type it again when prompted).
2. When asked by the bot, enter the error message.
3. Select I still need a human, then proceed with Contact us or Get help from a human.
4. Choose either Chat or Callback.

I also added these links on how to review the transactions and reconcile the accounts:

• Categorise and match online bank transactions in QuickBooks Online
• Reconcile an account in QuickBooks Online

Post again here if you need more help with this. Take care!
