Hello everyone. Today I changed my phone, transferring my data from an iphone 13 to an iphone 15 pro max. I wanted to put the stock wallpaper of iphone 15 pro max (the one in the picture below) but I can't find it. I also searched in the Collections section but can't find anything. I thought one cause could be that I currently have ios 18 beta 18.0.6 installed but I don't think so, do you know how I can fix it?
