My Simple Business Dashboard only shows Bank balances but not Tiller balances for each account. Restoring the Dashboard has not helped. Note that there is a difference between columns allocated to the two vertical sections in your Comprehensive Guide and My Simple Business Dashboard:
Comprehensive Guide My Sheet
Tiller Money Columns A to J Columns A to H
Simple Business Dashboard Columns K to V Columns I to T
It seems that the Dashboard part is covering up 2 columns where Tiller balances would be shown.
