Affinity iPad Student

I really appreciate you "literally" taking time out of your day to do that for me - THANK YOU!! However, can you please show me what I did wrong with either annotations or an existing guide - to this exact problem? Therefore, I'll know what I'm doing in the future. Thank you again guys, you've all been hero with the help.

Sure, How do I do that? I'm using iPad Affinity app. Thank you.

UPDATE: Resolved Definitely my fault, layered it wrong, in the layering sequence system. ORIGINAL POST: Hello community, I'm using iPad Affinity Photo I'm brand new to this photo editing. Never used adobe photoshop or any other photo editor - the most I've done is annotating on photos and cropping. Be mindful of this when speaking to me and using jargon that only a experienced would know. Approach me like a five year old child - if that's too much for you, you may not want to contribute to this thread. My problem: In the attached image, I am trying to make the picture with the brick top, part of the picture in the background (blend it in seamless) unfortunately, the white background is refusing to leave? Highly frustrating. I've checked out some YouTube channels and even the excellent tutorials provided in the app itself, somehow, someway I'm missing something here. Can someone help me please. Thank you.
