I am trying to snap receipt photos with the app. I see the whole receipt on my phone screen. But when I press Take photo, only a small portion of the receipt is snapped.

Thank you. I reinstalled the app, cleared the cache, restarted my phone.

More details of the problem:

I place a white receipt on a black paper on my table

I position my phone above the receipt

I see a green rectangle around the receipt's edges (but that rectangle is not very stable, it tends to jump all over the screen very often)

I click on the Take photo button

The result: a photo of the same size as the green rectangle, but its contents only show a partial photo of the receipt (for example, only the top 10% of it, or only the dollar amounts, etc.)

My phone is an S22, but this issue was also happening on my S20.
