I used to be able to delete (erase) a background on any image and save it to my photo album with a transparent background. I can no longer do this with any of my photo editing / illustrating software - on any of my devices... Regardless, I am asking for help with how to do this on my iPad Pro 12.9 using Affinity Photo - I have tried, and it continuously saves with a white background no matter what settings I adjust/change etc. (So frustrated.) Your help with this will be greatly appreciated. Thank you!
