It's still not 100% clear to me, but I definitely see what you're saying. I know there's no album reference, but it seems entirely possible that Image files returned are
all from a specific album, without having to choose them one-by-one. That seems entirely consistent with the API, the only question is the actual Picker interface.
If Google really has removed the ability to share all photos from a picked album, that's so idiotic I just don't get it. I don't see what possible benefit there is to security or to Google here. Why would Google screw over users for no reason at all? Companies generally remove features for a strategic reason. They don't upset consumers just for the fun of it.
Also, their blog post [1] clearly states, emphasis mine:
"The Picker API offers a secure and intuitive way for users to search for and select photos and albums through a seamless integration with the Google Photos app."
Does anyone have a link to the actual picker in action? And if it's missing selecting an album, is this intentional or an oversight that will be quickly corrected?
