I was just about to post a similar topic and this came up. I use Monzo as a spending account and transfer funds in via Faster Payments. I wanted to add up the positive, incoming transactions to see if a single standing order might be better, and couldn’t find a way to do so. Selecting me in the ‘person’ tag just shows all transactions since the start and I coudn’t identify this month’s.
It was quicker to go through manually.
