You can use the "Full Page" option to ensure that receipts take up an entire page instead of appearing in a 2x2 grid. You can do this like so:
- When creating a new receipt, tick the "Full Page" checkbox towards the bottom of bottom of the input
- If you need to change this setting for an existing one, you can tap on the receipt to edit it and then check the "Full Page" option
If you want to use this value by default, you can also enable the "Assume Full Page" option in the settings menu.
