"Balances" tab is borked - how do I restore functionality?

I think it is worthwhile, @TomWIN. The future of our platform is Tiller Money Feeds. We still support long-time users (thanks for sticking with us!) with feedbot sheets, but eventually we will want everyone to migrate so they can take advantage of many platform improvements.

The basic steps are to create a new Tiller Money Feeds spreadsheet in the Console then use the very recently-updated Migration Helper (in Tiller Labs) to port your data (e.g. categorization) from your old (feedbot) spreadsheet.

Heather has written some support content on this.

Let me know if you have any question,
