In Monzo Business, you select a category for the transaction. You’re then offered the option of using that category “from now on” and this option is in the middle of the screen (with “this payment” on the right of it).
You then also need to select a tax category, and you’re offered the option of using that category “going forward” except this time this button is on the right, with “this payment” in the middle.
I don’t mind which position but it would be much easier if they were in the same position for both times you select. At the moment it’s confusing and you have to carefully read the text. It would be most intuitive for this payment to be in the middle, and " going forward/from now on " on the right.
