Blank photos added in iOS app

[ArturLange]

What

When adding and scanning products on the iOS app, some of the photos do get uploaded but as a plain white background and nothing else. This tends to happen on slower networks, also the blank picture is not always the last one (which would make more sense - invalid upload due to closing app).
Example product:
https://world.openfoodfacts.org/product/4047902003872/thompson-jumbo-rodzynki

Steps to reproduce the behavior:

1. Be connected to a slow network
2. Add new product in the mobile app
3. Upload some photos

Expected behavior

I'd expect the app to upload the actual photo
