Some financial institutions have security safeguards that prevent third party applications like Acorns from monitoring your transactions for Round-Ups.
 
While Acorns can’t make recommendations to change or disable security settings with your online banking account, these features may prevent Acorns from successfully Rounding-Up your purchases and rewarding Found Money.
 
After changing any of these settings, unlinking and relinking should update your connection.
 
Please complete the following steps to link a Round-up Account: 

1. In the upper right corner, click on the Personal Avatar icon
2. Select Settings
3. Under Personal, select Linked Accounts
4. Under Cards & Accounts, select Add Account
5. Search for your bank
6. Connect using your banking credentials
