Tiller update the Balance History sheet with new balance data if it's available when you fill your sheet. However, if you notice a stale “last updated” date on the Accounts sheet for an account here are a few things to check.
If you notice that the update date is older than about a day:
Check for a duplicate account
Review your list of accounts and check for a duplicate instance of the account that has a stale "last updated" date. Sometimes duplicate accounts appear when you remove and re-add an account on the Tiller Console.
Initiate a refresh from the Tiller Console
Log in to the Tiller Console
Scroll down to the Account Summary
Click the blue “Refresh” button next to institutions that haven't refreshed in the last 36 hours. White refresh buttons indicate a refresh in the last 36 hours.
Open your spreadsheet and click “Fill sheets” in the Tiller Money Feeds add-on sidebar or click "Fill" in the Excel add-in sidebar to pull in the latest balance. Feed Bot sheets should pull balances automatically.
If the above tips don't refresh the balance data reach out to firstname.lastname@example.org to let them know which account specifically is missing recent balances.
