Saving pictures from websites to my phone should not require both Read and Write Photo Library access. That is excessive access that potentially compromises security. This behavior recently started, as far as I can tell, so this may be a bug, instead.
Also, the ability to save pictures from websites appears broken most of the time. The option used to show up all the time, and now it doesn’t show a menu or only offers to save a link. This is even when Read and Write Photo access is given and Scripts are turned on. Please give us this ability again.
