I have targets for monthly spends set up in my trends. I had no idea what my spending was so guestimated. After a few months I had better insight (the system works!) and I edited the amounts.
When I buy something with my card I get an instant notification on my phone screen along the lines of you have just spent £12.45 at Shop X. You have £45.55 of your grocery budget left.
However, these messages are based on the OLD totals. It’s a bit irritating.
Help?
Tap on your account, and then tap the pie chart top right of the screen and edit the amounts there.
Thank you so much! Sorted!
I recommend deleting all ‘budget/target/reporting’ data from ‘Summary’ (Pie chart) and setting up ‘Trends’-only reporting instead.
Summary (Pie chart) will… at-some-stage-although-inexpicably-being-dragged-on-for-years… be ditched in favour of Trends. But in true 
MVP style, by the time ‘Summary’ is deprecated, Trends will have been semi-replaced with another half-baked planning solution anyway.
