For the ‘bills’ category, most payments appear under Committed spending, but some payments (my internet/phone/TV) are paid by card so they appear separately under Spending.
For ‘groceries’, I have a budget but some is spent at the supermarket and some with a recipe box service. The latter appears in Commiitted spending, and doesn’t show against the budget.
Payments that are classified as Committed spending can fluctuate month to month / week to week.
It would be great to be able to set a budget and see total spend against that, committed or otherwise.
