App error while removing a picture

Hello forum !

I would like to delete some photos that I have uploaded. I use the Android app for this, using the report button shown at the bottom right of the image.

When I select a reason (whatever it is), an error message is displayed:
An error occurred while reporting. Please try again later.

I have tried several times, but the message is always the same. Do you know how to delete an unwanted photo?

Thank you !
