If you get a notification that says "Linking Failed. Please try again" when updating financials using QuickBooks Online, try the following:
1. Try again. The majority of the time linking works as expected the second time.
If you keep getting the error, try the following:
1. Press Update Financials
2. Press Disconnect
3. Press Update Financials again. This time you will be prompted to log into your Intuit account and linking should succeed.
