Also, your problem might be fixed by a little "edit page" button in the group gallery. If you click this button, you can move deviations the way it used to be

Come on DA get your act together and stop trying to destroy the site by pandering to mobile apps.
As a group Admin, being able to move images from one gallery to another is essential. Please re-enstate the edit feature, or you will kill the groups.
Also stop streamlining the system for Mobile devices. being able to fave pics without opening the page will not encourage to comment on each others work. So many site had done the same, and that is why I came back to DA. please stop trying to kill the groups and community spirit of DA. Da is a special unique site and should be proud of that fact. We are not just another social media site like flickr or tumblr
