Copy from Files to Photos function missing from iOS 13.1.2
I upgraded my iPhone to iOS13.1.2 and the ability to copy a photo from Files to Photos is missing- it insists I open the photo in an app such as Instagram. This is worrying as copying Photos to and from my computer via files>photos was an important part of my workflow. I have looked through the iOS 13 manual and cannot find a solution.
Does anyone know of a workaround? Thanks in advance.
